New York ? Time served and well behaved, but maybe too old to change.

Edward Magenheimer, 70, was out of Westchester County jail for less than 24 hours when he was arrested Tuesday for allegedly stealing a luxury car left running outside a deli, police said.

Magenheimer was spotted about 6:20 a.m. driving the white car in the suburbs about 20 miles north of Manhattan and was taken into custody, police Sgt. John Barbelet said.

The septuagenarian, who recently underwent heart bypass surgery, had just been released from jail on Monday after a one-year sentence for conning three women out of thousands of dollars. He pleaded guilty to the scam in July and was released early for time served and good behavior, authorities said.

Magenheimer was charged with third-degree criminal possession of stolen property, a felony, in the theft of the car, a 1996 Jaguar, police said.
