At least nine people were killed and dozens injured in a shooting at a high school and a residence in northeastern British Columbia, Canadian police said Tuesday. The suspected gunman is dead, officials said.

The school shooting was first reported at 1:20 PM PT at Tumbler Ridge High School, Royal Canadian Mounted Police he said in a press release.

Authorities responded and found six people dead at the school, RCMP said, and a seventh person died while being transported to hospital.

Police also responded to a second crime scene at a home believed to be related to the school shooting, where two more people were found dead, RCMP reported. The exact nature of their injuries was not immediately released.

Two other people from the school shooting were airlifted to local hospitals with serious or life-threatening injuries, police said.

The suspected gunman was found dead at the school from “self-inflicted injuries,” Canadian police said.

About 25 others were treated at a local medical center for non-life-threatening injuries, RCMP said.

Police earlier asked residents of the town of Tumbler Ridge, which has a population of about 2,400, to stay inside as additional police resources were deployed to the area from neighboring areas. The community-wide alert was canceled at 5:45 p.m., and investigators believe there are no suspects in the incident, RCMP said.

The Peace River South School District said Tuesday that a “lockdown, security and containment” was in place at Tumbler Ridge Middle School and Elementary School.

The provincial government website says Tumbler Ridge High School has 175 students in grades 7 to 12.

Larry Neufeld, member of the legislature for Peace River South, told reporters at the legislature that “surplus” resources, including RCMP and EMS assistance, have been sent to the community.

He said he did not want to release more information because of concerns it could compromise the security of the ongoing operation.

He urged those in the community to stay where they are.

“We understand that there are several people out there looking for loved ones, and once again, please go back to your homes and take shelter in your place and let the amazing people of the RCMP make this community, this beautiful community, safe again,” he said.
