Transit Police report arresting an East Boston man they say made a point of showing his genitals to women on the T - once while possibly freeing up one hand to video his victim's reaction.

According to police, Farid Ennagi, 44, took out his penis on a Green Line trolley and "committed a lewd act" in front of a woman, around 3:30 p.m. on Jan. 31. He repeated his performance around 4:10 p.m. the same day on a Green Line trolley near Kenmore Square. "The victim also reported she believed the suspect male video taped her reaction," police say.

Around 4 p.m. on March 12, this time on the Blue Line, police say, Ennagi "positioned himself directly in front of the victim and exposed his genitals to her" before exiting at Maverick.

Police say that detectives zeroed in on Ennagi and arrested him at Maverick station yesterday on a charge of open and gross behavior.

Innocent, etc.
