We’re surprised that news of this didn’t trickle out via local message boards or email lists, but there’s apparently a flasher on the loose in Park Slope. “The man exposed himself to a 14-year-old girl after pushing his way into her apartment building two weeks ago. ‘I’m not gonna hurt you; I’ve got something to show you,’ the pervert said, flashing the terrified teen in the doorway and chasing her up the stairs…78th Precinct detectives are on the case looking for the flasher, described as in his early to late teens, wearing black shorts, a gray T-shirt and a blue hat.”–NYDN
