A man has been arrested in Petawawa, Ont., after a multiple stabbing left one man dead and two females critically injured on Friday.
Petawawa residents were told to stay inside and secure their homes while police combed the town searching for the suspect.
Ontario Provincial Police received a 911 call just before 11 a.m. Friday.
When officers arrived at a home on East Street at Petawawa Point near the Ottawa River, they found a man dead inside.
Sources told CBC News two other people, both female, were critically injured. They were taken to hospital.
It was unclear if all three victims were found in the same home.
Helicopter, canine unit used in search
A helicopter and a canine unit, as well as officers on the ground, searched the town with assistance from military police for a suspect believed to be armed and dangerous.
A man was arrested just before 1:30 p.m. and was assessed by paramedics.
"[It was] chaos — police officers all over the place, flying up the hill because they heard something about guns at the school," said Petawawa resident Dan Reade.
"Traffic's been diverted all over the place, it's just been a hectic area around here right now."
The Renfrew County District School Board said in a statement that several of their Petawawa schools were placed on lockdown during the incident. The lockdown order was lifted around 2 p.m.
