WARREN, Pa. -- Authorities were searching Saturday for an inmate described by police as “very dangerous" who escaped from a jail in northwestern Pennsylvania using bed sheets, officials said.

Michael Burham was last seen wearing a blue denim coat from the jail, white and orange pants, and orange shoes, Warren police said Friday.

Burham was being held on arson and burglary charges and was a suspect in a homicide investigation, police said. He was also associated with a prior carjacking and kidnapping of a local couple, police said.

“He is considered very dangerous, and the public is asked to be vigilant and report anything out of the ordinary,” police said in a Facebook post.

Officials say he escaped by climbing on exercise equipment and using bed sheets tied together.
