Police say a man has walked into an aboriginal government office in British Columbia and attacked the people there, leaving 10 injured, some critically.

Police say the suspect was restrained when they arrived and died some time after the Wednesday attack.

Michaela Swan with the Interior Health Authority said that two patients are in critical condition, another two in serious condition and six others have non-life threatening injuries.

Royal Canadian Mounted Police say they were called about a man with a weapon at the Bridge River Indian Band office. They say they found the suspect already restrained when they arrived, but he was unconscious and unresponsive.

Police say they immediately started resuscitation efforts, but the man was pronounced dead at the scene.
