(WOOD) Officers who arrested a man who died shortly after arriving at Michigan's Kalamazoo County Jail initially thought he was acting, newly released video reveals.

The video, both from the dash camera and the camera directed at the back seat of a patrol car, was obtained from the Kalamazoo Department of Public Safety via the Freedom of Information Act. It shows the moments that led up to the May 6 death of James Dunigan.

Dunigan, 57, was treated at Bronson Methodist Hospital for chest pain and released around 4:30 a.m. He remained in the hospital lobby, moving around and switching chairs, staff told officers.
