   A Detroit teen was stopped during an alleged robbery at a Chase bank on the west side Monday after a quick-thinking teller locked him between a set of automatic doors until police came. 
   
   Detroit Police Officer Dan Donakowski said the 15-year-old boy walked into the bank located in the 15000 block of West 7 Mile around 2 p.m. and demanded money. 
   
   Donakowski said the teen gave the teller a note and threatened to use a bomb if she didn't fork over the cash. 
   
   "The teller complied, gave him some money and as he attempted to leave, the teller hit the button for the doors that automatically lock and the suspect was trapped inside," Donakowski said. 
   
   The teen was detained by police and transported to a juvenile facility, he said. It's unclear if the teen had a weapon, Donakowski said, adding that he believed the teen only had a note in his possession.

   Police say a 16-year-old, of Detroit, entered Chase Bank located on Seven Mile on Detroit's east side about 2:30 p.m. Monday. 
   
   He walked up to the counter and told the teller he was strapped with a bomb and to give him all the money, Detroit Police Officer Jennifer Moreno said. 
   
   The teller did. The teen set off for the doorway, likely exhilarated by the scent of escaping with his new wealth. 
   
   He opened the first set of doors into the causeway. The sidewalk was only steps away. He made it to the outermost set of doors, inches from the outside world. 
   
   He'd make it no further. After realizing they wouldn't budge, he tried to retreat through the door he'd just passed. They wouldn't budge either. 
   
   The teller engaged what is called a "man-trap," basically a security system that locks would-be intruders between the two sets of doors leading outside where they remain caged until police can arrive and take them safely into custody, which Detroit police soon did. 
   
   Often the glass is also bulletproof. 
   
   It's not clear if the teen will face charges as a juvenile or in the adult court system.
target: – A teenage would-be bank robber in Detroit found himself imprisoned—and presumably regretting one or two life choices—within seconds of being handed money at a bank on Monday, police say. A police spokesman tells the Detroit Free Press that the 15-year-old gave a teller a note claiming he had a bomb and demanding money. As he left with the cash, the teller hit a button that trapped the youth between two sets of doors. The security system, known as a "man-trap," keeps intruders caged until police arrive, MLive reports. Police say the teen, who didn't have any explosives on him, was taken to a juvenile detention facility. (A man who stole a restaurant's tip jar ended up losing money.)
