A man who police say took a 12-year-old girl to a motel room and molested her was arrested Saturday night.

The girl and two friends, aged 13 and 14, were picked up by the 22-year-old man at an undisclosed Smith's store Saturday evening, said Salt Lake City police detective Robin Snyder. Investigators were still trying to determine Monday if the girls were hitchhiking or if the man who gave them a ride was an acquaintance.

The girls asked for a ride to The Gateway, but the driver instead took them to the Chateau Motel and Trailer Court, 1999 W. North Temple.

While there, one of the girls called her parents on her cell phone about 8:30 p.m. and they in turn called police, Snyder said. Police arrived with all four people still there and arrested the man.
