Police released body-cam video showing officers' encounter with a stabbing suspect on Jan. 30. The incident happened inside a Safeway grocery store near Litchfield and Indian School Roads.

The perpetrator of the attack, Zaheer Mahmood, 29, hadn't realized that the satirical weekly magazine had moved offices and wounded two employees of another agency.

Police killed three suspects during raids on Friday — one wanted in the fatal shooting of a policewoman and four hostages, the other two in the massacre at the offices of Charlie Hebdo magazine.
