The Brooklyn Bridge was closed off on Sunday as police and firefighters responded to a water rescue that turned out to be a false alarm made by a brazen prank caller.

The pedestrian walkway was evacuated when police received a call around 4:38 p.m. from someone they believe was an emotionally disturbed person who reported a gunman was about to jump in the water from the bridge, according to police sources.

NYPD Harbor responded to the call and was looking for someone who jumped in the water. There was also a report made of a suspicious package that turned out to be a Food Bazaar bag, sources said.

FDNY said they had no patients.
