BROOKLYN - Cops are on the hunt for two pairs of suspects in connection with separate robberies in Brooklyn.

Police released a photo of two men who they say stole electronics from the wall at an Infinite Wireless store on Sheepshead Bay Road. An employee tried to stop them, but one of the suspects threatened to stab the worker with a knife.

Another two men were also caught on camera when they held up a store called La Fogata on Gates Avenue. The armed suspects demanded employees get down on the floor, and stole a cell phone and money.
