Transit Police report arresting a Weymouth man for the sort of crime that might make the parents of a young child think twice about ever getting on the T again.

According to police, the parents and their 2-year-old daughter boarded an inbound train at Wollaston around 6 p.m. - to the sounds of a couple across the train arguing with each other. Police say the male yeller, Joseph Pacheco, 43, of Weymouth, twice took a moment off to ask the father for a cigarette. The second time, police say, Pacheco leaned over the toddler's stroller:

The female victim/mother of the 2 year old demanded Pacheco back away from her daughter. Pacheco's female companion took exception to this request and began assaulting the female victim. The male victim intervened and was then attacked by Pacheco, at this time the train was pulling into Broadway station and the female victim along with her young daughter were able to vacate the train. Pacheco and his female companion continued to assault the male victim, this time however Pacheco attempted to strike the male victim with a 40oz container of beer. The victim was able to elude the beer bottle and it shattered against the train wall.

Transit Police officers arrested Pacheco on charges of assault with a dangerous weapon (the beer bottle) and assault and battery. Turns out he was also wanted on a warrant for shoplifting. He's scheduled for arraignment today in South Boston District Court. His female companion managed to elude police.

Innocent, etc.
