Armed with a metal chain, these masked men tied open the emergency door at a subway station in Brooklyn.
Police say these pranksters also taped over the MetroCard readers.
They even posted fake signs that looked like official MTA notices, indicating customers ride for free.
Investigators say the suspects tampered with turnstiles and emergency exits at three subway staitons on Wednesday: the 116th and Lexington station in Harlem and the Beverly Road and Fort Hamilton Parkway stations in Brooklyn.
Police also released video they say shows the suspects leaving one of the stations without their masks.
They're also looking for a man seen snapping pictures of the pranksters in the act.
Subway riders we spoke to were not amused by the prank.
"I like to pay my own way," said Albert Delgado. "That's part of being responsible. You don't want to get in trouble. I don't want to get in trouble because if you go through and the police are there, you will be arrested and given a ticket."
