Police have released surveillance video of two men wanted in a string of cab driver robberies in Brooklyn.

In one of the cases, police say a driver picked the two men up on Dec. 10, on Bay Ridge Avenue.

They say one of the men pulled out a gun and forced the driver to hand over his cellphone and money.

Police say the men are also accused of robbing a livery cab driver in Coney Island on Dec. 6. 

The men threatened to beat up the cab driver and demanded money. 

Both drivers were not injured during the encounters, police say.
