Madison police said a thief who took a purse from a woman’s truck and left behind a stolen car was spotted by a concerned citizen and arrested.

Police said a 36-year-old Madison woman left her car running outside her Londonderry Drive home to warm up Christmas morning, and it was stolen.

The same car was later used in a gas drive-off, police said.

On Saturday night, a 49-year-old Madison woman was pumping gas into her truck at a station on Pflaum Road when her purse was taken from the front seat. The thief fled on foot, leaving behind the car stolen on Christmas Day. The gas station clerk was able to provide police with the thief’s description.

A short time later, a concerned citizen reported a suspicious man lurking around vehicles parked in the 1300 block of Tompkins Drive. Police said the man was attempting to get someone to give him a ride, and he matched the description of the thief at the gas station.

Police arrested Donald D. Alford-Lofton, 19, of Madison, on suspicion of theft from a motor vehicle, operating a vehicle without the owner’s consent and possession of drug paraphernalia.

Officers said Alford-Lofton had the victim’s cellphone and case in his pocket and a key to the stolen car. He wouldn’t tell officers where the victim’s purse was.
