A video surfaced on Twitter late last week, of a young person being punched repeatedly and forced from her seat.

The Ottawa Police Service has charged a young offender in an incident on a Trillium Line O-Train.

A disturbing video was recorded on the train last Friday, September 7, showing a transgender teen girl being repeatedly punched by a teen boy.

In the video, the girl is seated when a boy standing next to her begins throwing punches repeatedly, and shoving her out of her seat.

The girl then gets out of her seat, and is standing with her back to the boy when he punches her in the back of the head as she walks away.

Multiple onlookers are then seen cheering.

The Ottawa Police Service confirmed it was investigating the incident on Thursday, and confirmed that charges had been laid early Friday morning, September 14.
