EAST MEADOW, N.Y. –  Authorities on Long Island say an 83-year-old man has been arrested after checking himself out of a hospital and stealing an ambulance, reported Fox News.

GovXPolice say Donald Winkler, of Merrick, was upset with the quality of care he was receiving. Consequently, he checked himself out of Nassau University Medical Center around 1 a.m. Tuesday. But he was apparently without transportation.

Winkler found an ambulance parked with the keys in the ignition, so it appeared to be a feasible option. Investigators say he then stole the emergency vehicle from the hospital parking lot.

Police say they later found the disgruntled patient at a nearby 7-Eleven. According to police, he admitted taking the ambulance.

Winkler was arrested, taken back to the hospital and evaluated. Police arraigned him at his bedside. It is unknown whether he thought the quality of care improved.

Winkler was charged with second-degree grand larceny.
