Washington (CNN) -- A man who jumped the White House fence on Tuesday was apprehended by uniformed Secret Service officers who approached him with guns drawn. 
 
 The incident was broadcast live on CNN's "John King USA" program, which was produced from the North Lawn of the White House on Tuesday night. 
 
 After the man jumped the fence, armed officers ordered him to lie down and then handcuffed him before taking him into custody. A backpack thrown over the fence and lying on the ground nearby was being checked by security officers, who locked down the area as a precaution. 
 
 The incident ended shortly after 9 p.m. ET when authorities issued an all-clear directive at the White House. 
 
 There was no immediate information on whether the intruder had represented a security threat. 
 
 According to the Secret Service, the detained man is James Dirk Crudup, 41, who is homeless. He will be charged with unlawful entry and contempt of court because he previously had been ordered to stay away from the White House due to past incidents, the agency said. ||||| The spokesman, Ed Donovan, said Crudup would be charged with unlawful entry and contempt of court. The contempt charge was to be brought in connection with an order requiring the man to stay away from the White House. 
 
 Donovan said the man was “tackled immediately” by Secret Service officers, who provide security at the White House. 
 
 It was not clear why Crudup climbed the fence, and authorities did not think that he was armed. A backpack that apparently belonged to him was being examined Tuesday night, Donovan said. 
 
 CNN televised footage of the incident that showed a man prone on the White House lawn, a few feet from the metal picket fence. The man was in the custody of two uniformed Secret Service officers. 
 
 It could not be learned immediately where the president was at the time. The last event on his official schedule was set for 4:30 p.m. 
 
 Incidents such as Tuesday’s are not uncommon. In an unusual twist, a 6-year-old girl reached the lawn Sunday night by going not over the fence but through it. After slipping between the black metal pickets, she was escorted out to her parents by the Secret Service, authorities said. ||||| Story highlights A White House fence jumper had more than 800 rounds of ammunition

 The U.S. Secret Service boosted its presence and its surveillance measures around the White House on Monday after an Iraq war veteran, who is apparently suffering from PTSD , jumped over a White House fence. 
 
 Officers patrolling the area will be out in greater numbers and will be "looking for individuals who don't look like tourists," a federal law enforcement officer told CNN. 
 
 Two security incidents in two days have raised concerns about the safety at 1600 Pennsylvania Ave. 
 
 On Friday, Omar Gonzalez hopped the north fence and sprinted just past the north portico White House doors when he was stopped, Secret Service spokesman Brian Leary said. 
 
 Gonzalez carried a Spyderco VG-10 folding knife with a 3½-inch serrated blade in his pants pocket, according to an affidavit.

 He allowed authorities to search his car, where police say they found more than 800 rounds of ammunition in boxes and magazines. They also found two hatchets and a machete in his car. 
 
 A Secret Service officer said he yelled at the intruder to stop. Gonzalez told a Secret Service agent "that he was concerned that the atmosphere was collapsing and needed to get the information to the President of the United States so that he could get the word out to the people," according to the affidavit. 
 
 President Barack Obama and his family were not at home at the time. 
 
 Friday was not Gonzalez's first run in with police. In July, he was arrested in Wythe County, Virginia, and charged with possession of a shotgun and a sniper rifle. He was also charged with eluding and evading arrest. In addition, police say they found a map with the White House circled. 
 
 In late August, Gonzalez was stopped while walking along the White House fence. He carried a hatchet and allowed police to search his car, where they found camping gear and two dogs. He was not arrested then. 
 
 Deteriorating mental state 
 
 Gonzalez's former stepson told CNN's Mary Grace Lucas that Gonzalez is an Iraq war veteran who suffers from post-traumatic stress disorder 
 
 Gonzalez did three tours in Iraq and is a "great, great guy," his ex-stepson, Jerry S. Murphy, said. He said the knife that was found in Gonzalez's pocket was a weapon the veteran routinely carried. 
 
 Murphy said Gonzalez's eight-year marriage to Murphy's mother ended two years ago, confirmed by marriage records. 
 
 He said he last spoke to Gonzalez around the time of the split but knows that Gonzalez was seeing a therapist on base at Fort Hood in Texas. Murphy said his former stepfather was diagnosed with PTSD and paranoia, and his base psychiatrist had prescribed medication for both conditions. 
 
 Murphy views Gonzalez as a "hero" who took great pride in serving his country. 
 
 But after each deployment, Gonzalez's mental state seemed to deteriorate, Murphy said. 
 
 Gonzalez is accused of unlawfully entering a restricted building or grounds while carrying a deadly or dangerous weapon, officials said. 
 
 He appeared Monday in court, where a judge decided Gonzalez was a flight risk and a potential danger to the President. He will be held in custody until his next hearing, scheduled for October 1. 
 
 Minutes before Gonzalez jumped the fence, the President and his daughters left the South Lawn by helicopter. It is not clear where First Lady Michelle Obama was, but officials tell CNN that the family was staying at Camp David, Maryland, for the weekend. 
 
 Another security incident 
 
 In the second security incident over the weekend, Kevin Carr is accused of driving up to a security barrier Saturday and trying to walk to and enter the White House. 
 
 Carr, of Shamong, New Jersey, was arrested and charged with unlawful entry, Leary told CNN. Records show Carr was born in 1995, making him about 19 years old. 
 
 According to Leary, the incident happened at the entrance at 15th and E streets, where the driver did not stop when the Secret Service ordered him to do so. 
 
 The man's car did not hit the barriers at the entrance, and the driver got out of his vehicle. Carr was arrested after he refused to leave, Leary said. 
 
 The Obamas were not at home at the time of the second incident either. 
 
 Criticism of White House security 
 
 The Secret Service said Gonzalez should have been stopped faster and are investigating personnel and reviewing security policies and procedures. 
 
 Rep. Peter King, R-New York, demanded a full investigation and called for a congressional hearing to ensure that changes are made. 
 
 "There can be a lot of conspiracies against a President. A lot of very complex assassination plots," King said on Fox News. "This is the most basic, the most simple type of procedure and how anyone, especially in these days of ISIS, and we're concerned about terrorist attacks, someone could actually get into the White House without being stopped is inexcusable." 
 
 In a statement from White House on Saturday night, spokesman Frank Benenati said the President expressed his support for the Secret Service. 
 
 "The President has full confidence in the Secret Service and is grateful to the men and women who day in and day out protect himself, his family and the White House," the statement read. 
 
 "The Secret Service is in the process of conducting a thorough review of the event on Friday evening, and we are certain it will be done with the same professionalism and commitment to duty that we and the American people expect from the USSS."
– A homeless man was arrested after hopping the White House fence Tuesday night in an incident captured by CNN's John King USA program, which was filming from the North Lawn. The man was quickly taken into custody by Secret Service agents who approached him with guns drawn. Security officers locked the area down after finding a backpack that had been thrown over the fence nearby. The 41-year-old intruder was charged with unlawful entry and contempt of court for breaking a judicial order requiring him to stay away from the White House. It's not uncommon for the White House fence to be breached, notes the Washington Post: A 6-year-old girl made it onto the White House lawn over the weekend by slipping through the fence instead of going over it. Secret Service agents returned her to her parents.
