A wild surveillance video shows a Chicago inmate crashing a stolen ambulance that he used to escape from custody.

The Associated Press reported that 23-year-old Michael Buckner was being transported to a hospital after having a medical issue while in police custody. 

He then allegedly stole the ambulance, driving into Wisconsin, where he crashed north of Milwaukee. 

The Associated Press reported:

According to the sheriff’s office, a bystander stopped to help Buckner and offered him a ride, but he stole the vehicle and drove it a short distance before being taken into custody.

Wisconsin authorities say Buckner appeared to have a medical issue while in jail and was taken to a hospital, where they say he attacked deputies.

Police say Buckner faces charges in Illinois. It wasn't immediately known if he has an attorney.
