BOSTON (WHDH) - A Haverhill man was arrested Monday after police say he exposed himself and urinated on the floor a Commuter Rail train.

Officers responding to a report of a man exposing himself at the MBTA’s North Station about 1:55 p.m. were met by victims who said a man traveling on an inbound Haverhill Line Commuter Rail train stood at the head of the car, lowered his pants and underpants and began to urinate on the train car floor, according to transit police.

The witnesses said the man urinated in view of approximately 30-40 other patrons on the train.

Keolis personnel pointed out the man to transit officers, who quickly placed Keith Comeau, 38, of Haverhill, into custody inside North Station on a charge of open and gross lewdness.
