MADISON, Wis. -- Authorities said a drunken man stole an ambulance from a Wisconsin ski area with the patient and paramedics still inside.

The Dane County Sheriff's Department said emergency responders were treating a patient in the back of the ambulance at the Tyrol Basin Ski and Snowboard Area in Mount Horeb on Monday night.

They said Nicholas Pontillo, 24, of Lake Villa, Ill., got into the vehicle and drove it around the parking lot.

The sheriff's department said deputies arrested the man. But it is unclear how he was stopped.

Fitch-Rona Medical Service Deputy Chief Dale Dow said the ambulance's emergency brake was on and paramedics were still in the back when the man got inside. He said he doesn't know what happened after that.

Authorities said Pontillo was arrested on charges of operating a motor vehicle without owners consent, disorderly conduct and operating while intoxicated. Pontillo also has two outstanding warrants from Kenosha County for operating after suspension and failure to notify police of an accident, according to officials.

He is currently being held in the Dane County Jail.
