The mother of an 11-year old boy who is in critical condition in hospital is facing multiple charges including attempted murder after an assault at a west-end Toronto apartment early Friday, police say.

Police said the boy had been beaten. His mother is now facing charges for aggravated assault and failing to provide the necessities of life in addition to the attempted murder count.

Police, who responded to reports of a fight from neighbours, were called to an apartment building on Eva Road — near Burnhamthorpe Road and The West Mall in the west-end neighourhood of Etobicoke — at around 1:15 a.m. ET Friday.

They smashed through the glass door at the building's entrance to get to the 12th-floor apartment, and found the boy with cuts and bruises.

A neighbour told CBC News that her sister-in-law heard the commotion and called police, who were already en route to the building.

"She heard someone screaming, someone hurting," the woman told CBC's Trevor Dunn.

Boy to undergo surgery

The boy was taken by ambulance to the Hospital for Sick Children, where he is scheduled to undergo surgery on Friday.

Shortly after the boy was taken away by ambulance, two women — one of them the boy's mother — left the building in police custody. Only the mother remained in police custody as of 11:30 a.m. ET.

Neighbours say the boy lived in the apartment with his mother, an older sister and a younger brother. 

Two other children in the apartment were also taken away.

Neighbours told CBC News that one of the women under arrest was behaving strangely as she was taken into custody.

"She was in the back of the cruiser and blowing kisses and smiling, like she was on drugs or something," a man told CBC.

The Children's Aid Society has also been contacted.
