 Junead Khan, 25, planned to stage a road accident with American soldiers before attacking them with knives and potentially detonating a bomb, Britain's Metropolitan Police said after the verdict. 
  
 Junead Khan's uncle, 23-year-old Shazib Khan, was also found guilty of planning to travel to Syria to fight alongside ISIS, according to the police statement.

 The pair, both from Luton, north of London, were arrested in July last year and convicted on Friday at Kingston Crown Court of "engaging in conduct in preparation of terrorist acts." 
  
 Junead Khan's work as a delivery driver took him near U.S. airbases in eastern England, according to The Associated Press. 
  
 Police said he sent a "chilling message" to a suspected ISIS fighter of how he had missed an opportunity to kill U.S. soldiers on one of his delivery rounds. 
  
 "When I saw these U.S. soldiers on road it just looked simple but I had nothing on me or would've got into an accident with them and made them get out the car," the message read, according to police. 
  
 During their searches, police also recovered U.S. and British flags stolen from an American-style diner, which investigators believe were going to be used for anti-Western symbolism during the attack.

 They also found an ISIS black flag and an article from an al Qaeda magazine entitled "Make a bomb in the kitchen of your mom," the AP reported. 
  
 Police visited Junead Khan four times in 2014 and attempted to steer him away from fundamentalist views. However he "refused help and instead became more embroiled in extremism," according to police. ||||| Story highlights British police posed as company managers and questioned the suspect's whereabouts, source says

 Junead Khan plotted to stage a traffic accident and use a knife to kill service member, prosecutors say 
  
 (CNN) British police mounted an elaborate undercover operation to seize a terror suspect's cellphone before it could lock and potentially become inaccessible, a source close to the investigation told CNN on Friday. 
  
 A goldmine of information retrieved from the phone, including communications with a British ISIS operative in Syria, played a key role in securing a conviction against Junead Khan. 
  
 The 25-year-old delivery driver , accused of plotting to kill U.S. airmen at the RAF Lakenheath air base in eastern England, was convicted Friday by a British court of preparing terrorist acts, according to the British Crown Prosecution Service. 
  
 British investigators feared that if Khan's iPhone 5S had become locked it would be very difficult to retrieve data, the source told CNN. Their quick action also helped avoid problems faced by the FBI after the San Bernardino, California, shootings in December. 
  
 The FBI was unable to gain access to gunman Syed Farook's locked iPhone 5C for almost four months. On Monday the Department of Justice announced the FBI had finally obtained access to data on the phone after an unidentified third party provided help. The FBI and Apple had been engaged in legal proceedings after U.S. authorities attempted to compel Apple to provide a technological solution to unlock the phone.

 A delivery driver from Luton has been convicted of plotting to kill a US airman outside a base in East Anglia. 
  
 Junead Khan, 25, a supporter of so-called Islamic State (IS), was found guilty of preparing terrorist acts. 
  
 Khan had driven past RAF Lakenheath and other US bases on his delivery route, and had discussed staging a car crash and attacking a soldier with a knife. 
  
 He was also convicted of preparing to join IS in Syria. His uncle Shazib Khan was also convicted of the same charge. 
  
 In what police called a "chilling message" to a suspected IS member, Junead Khan described how he had missed an opportunity to kill US soldiers on his rounds as a delivery driver. 
  
 The message said: "When I saw these US soldiers on road it just looked simple but I had nothing on me or would've got into an accident with them and made them get out the car." 
  
 His contact replied: "That's what the brother done with Lee Rigby" - referring to the British solider murdered in Woolwich in 2013. 
  
 'Embroiled in extremism' 
  
 During the trial, the court heard Junead Khan had been identified under the government's anti-extremism programme - and had mocked it after police visited him in 2014. 
  
 He sent a message to his 23-year-old uncle, Shazib, also from Luton, saying he was laughing out loud because police left a card asking him to call them. 
  
 He later met with officers and afterwards sent a message saying: "Hopefully the last I hear from them."

 Commenting after the verdicts, police said Junead Khan "repeatedly rejected police offers to help divert him from radicalism". 
  
 Officers working as part of Prevent - the government's drive to stop people becoming terrorists or supporting terrorism - visited him four times in 2014, the Metropolitan Police said. 
  
 But he refused help and became "more embroiled in extremism", and after his arrest police found material including "bomb making guides and terrorist propaganda". 
  
 Commander Dean Haydon, of the Metropolitan Police's Counter Terrorism Command, said Junead Khan had done extensive research on how to make a bomb. 
  
 Police also recovered British and US flags stolen from a diner in Dunstable. These were "potentially to be used for a symbolic act during the terrorist attack", the Met said. 
  
 In July 2015, Junead Khan had an encrypted online conversation with Junaid Hussain, a British IS operative in Syria.

 He was sent instructions on how to build a bomb and was told to use it against police if they arrived on the scene of his planned attack. 
  
 Days after this online conversation he carried out internet research into buying a large knife - but was then arrested at his workplace. 
  
 The following month Junaid Hussain was killed in a US missile strike - one of only a few British IS operatives who have been targeted in this way. 
  
 Hussain was a hacker and IS propagandist, and US military spokesman Colonel Steve Warren said he had the potential to "radicalise and inspire violence in foreign countries around the world". 
  
 Sue Hemming, head of the counter terrorism division of the Crown Prosecution Service, said: "Through early detection and prosecution of these individuals more serious crimes have been avoided which could have had devastating consequences in the UK or Syria." 
  
 The verdicts came after a six-week trial at Kingston Crown Court. 
  
 The men were remanded in custody and will be sentenced on 13 May. |||||

British police went undercover to trick a 25-year-old delivery driver into giving them his cellphone, leading to his conviction on terrorism charges Friday, CNN reports. Back in July, undercover officers posing as company managers showed up at Junead Khan's workplace and asked to see his work records. When they asked for proof of where he was on a certain day, he showed them a record from that day on his iPhone. They asked for a closer look then arrested Khan once he handed over the phone. So as not to be locked out, the officers quickly changed the phone's password, giving them complete access. Khan's iPhone ended up being a "goldmine of information." He used it to keep in contact with a British ISIS fighter in Syria, who sent him bomb-making instructions, the BBC reports. There was also an encrypted conversation in which he lamented missing an opportunity to kill US soldiers near a base on his delivery route. "When I saw these US soldiers on road it just looked simple but I had nothing on me or would've got into an accident with them and made them get out the car," NBC News quotes the message. Thanks in part to evidence on his iPhone, Khan was convicted of preparing terrorist acts and planning to join ISIS in Syria on Friday.
