Cops are searching for the man who attacked a train conductor at the DeKalb Avenue subway station on Aug. 10.
The victim was pulling into the station in a Coney Island-bound D-train when the scumbag walked up to her from the platform and asked her for directions at 7:20 a.m.
When she told the man he was on the wrong platform, the disoriented bozo got upset and punched her shoulder through the train window and flicked a lit cigarette at her before bolting, according to police.
The victim received treatment for her bruised shoulder at a nearby hospital, according to the authorities.
The man was wearing a baseball cap, a white T-shirt, cargo shorts, and black sneakers, according to cops.
