ARAPAHOE COUNTY, Colo -- A door-to-door salesman was has been arrested for investigation of theft and criminal trespass after Douglas County deputies said they found a stolen cell phone in his possession.

Deputies were called to the 8800 block of Chestnut Hill Place in Highlands Ranch on July 3 by a woman who said a cell phone and money had been taken from her car that was parked outside her home.

An investigation revealed that a salesman had been in the area earlier in the day and deputies began looking for the man.

A brother of the victim later called to say he had located the salesman in the area and deputies talked to the man, seizing a cell phone that matched the description of the one that had been reported stolen. A check showed the cell phone was registered to the victim.

Douglas County officials asked citizens to not leave purses, wallets and other valuables in their unlocked cars.
