ALBUQUERQUE, N.M. (AP) — Authorities say an Albuquerque ambulance worker catching some sleep in the back of his vehicle woke up to find himself the victim of a carjacking.

Police have arrested a man and a woman accused of driving off in the ambulance around 3 a.m. Saturday while it was parked outside Lovelace Medical Center in downtown Albuquerque.

Police spokesman Elder Guevara says the employee was asleep in the vehicle's rear but was able to jump out when the ambulance slowed near an intersection.

Officers then pursued the ambulance as it headed eastbound, and then westbound, on Interstate 40.

The ambulance finally came to a rest on I-40, over Tramway, after authorities used spikes to deflate the ambulance's tires.

Police have not released the names of the suspects or the victim, who was uninjured.
