Authorities detained a person who led them on a pursuit in a stolen ambulance in the Inland Empire Sunday evening.
The California Highway Patrol said the chase began when the patient was on a gurney and somehow escaped his restraints. He then managed to take over the vehicle and drove on the northbound 15 Freeway near Hesperia.
Officials were called to respond at around 4 p.m.
The individual exited the vehicle near the Main Street exit in Hesperia, where he was taken into custody.
Authorities provided no further information.
