An ambulance was stolen outside of Grady Memorial Hospital on Tuesday morning after the driver stepped away to drop off a patient, according to police.

Authorities have since found the ambulance but are still working to locate the person who drove off in it about 7:45 a.m.

The vehicle was left unattended outside the hospital at 80 Jesse Hill Drive while its driver was tending to a patient, Atlanta police said in a statement. The driver left the engine running while taking the patient inside, according to police.

When the driver walked back outside, the vehicle was gone.

Investigators placed a lookout notice on the stolen vehicle and recovered it in East Point, police said. It was towed to the Atlanta police Public Safety Annex for processing.

The investigation is ongoing.
