Problem:A "brazen" trio has robbed nearly two dozen Los Angeles area banks in the span of seven months and police, worried that the bandits' attempts may become violent, appealed last week to the public for help in catching them. 
  
 The suspects are still on the loose, Det. Joe Harris with the Los Angeles Police Department's Robbery-Homicide Division told NBC News Friday, a week after the department released security footage of the three men and asked the public to call in any information that might lead to their arrests. 
  
 The LAPD decided to release the videos because police have "had it" with the volume of heists connected with the group — 23 since November, Harris said. 
  
 "They're hitting all over the place," he said. 
  
 Typically, the thieves casually walk into their target bank and one hands a teller a note, according to the LAPD. "They demand money and claim to be armed while threatening violence if their demands are not met," said a statement from the department. 
  
 No one has been physically hurt to date by the robbers, who have been dubbed the "Cold Hand Bandits" because one of the suspects wore winter gloves during one of the first robberies, said Laura Eimiller with the Los Angeles FBI office. But authorities worry that the violent threats on the notes might become reality if the robbers don't get what they want.

 The FBI is working with the LAPD, along with the Los Angeles County Sheriff's Department, Alhambra Police Department, Pasadena Police Department and Long Beach Police Department to identify and catch the three suspects, who are considered "armed and dangerous," according to the LAPD. 
  
 "It is scary," said the manager of a bank that the "Cold Hand Bandits" have robbed twice. 
  
 The manager, who didn't want to be identified for security reasons, told NBC News she will be on edge until the robbers are caught, but the chance of robberies is always a fear. "Working with cash, that’s the worry that we have every day," she said. 
  
 The most recent robbery took place in late April and was a repeat performance at a bank in the city of Artesia that the suspects had robbed ten days earlier, according to security footage released by the LAPD that showed portions of five different robberies. 
  
 Footage from April 18 shows a single robber handing a teller a note and then exiting with a wad of cash she hands him. 
  
 In footage from April 28, one of the suspects wanders the lobby of the bank, brandishing what appears to be a gun, while another suspect jumps over the counter. At least two tellers drop to the floor as the robber behind the counter opens drawers, using his shirt in an apparent bid to avoid leaving behind fingerprints. 
  
 One teller gets up to open a drawer that requires a key, and the robber fills a bag with what appears to be cash before he and the man with the gun run out of the bank. 
  
 "This isn’t amateur hour," Det. Charles Geiger of the LAPD’s Robbery-Homicide Division told NBC Los Angeles. "The next level is people get tied up, maybe somebody gets hurt.” ||||| Published on May 20, 2016 
  
 Los Angeles: The Los Angeles Police Department Robbery Homicide Division is requesting the public’s assistance in identifying three suspects who have been involved in 24 bank robberies. 
  
  
  
 Los Angeles Police Department Robbery Homicide Division detectives have partnered with investigators from the Federal Bureau of Investigations, Los Angeles County Sheriff’s Department, Alhambra Police Department, Pasadena Police Department and Long Beach Police Department to identify suspects involved in a series of bank robberies which began in November 2015. The most recent robbery occurred in April 2016. The suspects enter the location and pass the teller a note. They demand money and claim to be armed while threatening violence if their demands are not met. In recent robberies, the suspects have become increasingly brazen and have jumped over the teller’s counter. Law enforcement is greatly concerned that the level of aggression the suspects are displaying is increasing as the bank robberies continue. 
  
  
  
 The suspects are described as male Blacks, approximately 25 to 30 years of age. Two of the suspects are between 5 feet 7 inches to 5 feet 9 inches tall and weigh 170 to 190 pounds. The third suspect is between 5 feet 6 inches and 5 feet 7 inches tall and weighs 140 to 160 pounds. All the suspects should be considered armed and dangerous.

Solution:
Police are hoping to find three men they say are responsible for robbing 23 Los Angeles-area banks since November before things turn violent, NBC News reports. According to CBS Los Angeles, the men have been dubbed the Cold Hand Bandits because they always walk into a bank with one hand in their pocket. They typically hand a teller a note stating they're armed and threatening violence, police say. One manager, whose bank has been robbed twice, says it's "scary." Police say the Cold Hands Bandits last struck April 28. Police say they've "had it," deciding Friday to release video of the suspects in hopes the public can identify them. “In recent robberies, the suspects have become increasingly brazen and have jumped over the teller’s counter,” CBS quotes a statement from police as saying. “The next level is people get tied up, maybe somebody gets hurt,” LAPD Det. Charles Geiger tells NBC Los Angeles.
