Ottawa police are investigating after a 17-year-old boy was attacked and slashed in Barrhaven, sending him to the Children's Hospital of Eastern Ontario.

Police said officers responded to Kennacraig Private just after 6 a.m. on Sunday after multiple 911 calls.

The calls reported a young man knocking on doors seeking help, police said.

Paramedics said the teenager was taken to hospital in stable condition with facial lacerations.

He is not co-operating with the investigation, police said.
