B’klyn flasher susp arrested

A serial flasher who exposed himself to half a dozen girls in Brooklyn since September is in police custody, cops said Tuesday.

The suspect, whose name had not yet been released, was wanted in a string of creepy episodes in Sunset Park.

On Wednesday morning, he allegedly flashed two girls, 11 and 13, as they walked a dog past the corner of Seventh Ave. and 18th St. The girls ran to their mom, who chased after him and snapped pictures as he fled.

Cops said they’ve linked him to at least five more incidents after releasing photos last week.

Typically, he’d expose himself to young girls while walking, or flash entire families outside their windows, police said.

The NYPD’s 72nd Precinct on Tuesday announced the arrest on Twitter. Charges were pending.
