Police have identified a woman who they say used her three-year-old daughter to hit a passenger on a Toronto Transit Commission streetcar.

The incident occurred on Friday at around 5 p.m. on a streetcar travelling along Dundas Street east near Broadview Avenue.

"She gets into an altercation with a [woman] on the streetcar and then she uses her child and takes her child and starts hitting the woman with her child," said Toronto police Const. Tony Vella.

The woman then pulled the hair of another passenger who tried to intervene, police said. The woman got off the streetcar at Broadview Avenue with the child and walked away.

Police believe the child was not hurt. But they are concerned for the little girl's well-being.

Police have identified the mother but are not releasing her name until they speak with the woman. So far, no charges have been laid.
