A 15-year-old girl who flagged down a police officer Monday said she had just been raped by a man who offered her a ride home from school at lunchtime.

The girl said she was walking home from Granger High School when a man she said she had met once before offered to drive her to her house. After accepting the ride, she said she was taken to the house near the school where he is staying with members of his extended family.Officer David Shopay said he was driving by the house just before 1 p.m. when the girl ran outside to see where the attacker had gone but spotted the passing police officer instead.

None of the other occupants was in the house at the time of the assault, and the suspect fled, leaving all of his belongings and a rented car, Shopay said.

The victim described the suspect as being 19, and one of the suspect's cousins said he is 22. Shopay said the suspect's family members said the suspect had been visiting in the Salt Lake Valley from his home on one of the Pacific islands.

Other violent acts at or near Granger High School lately have been linked to disputes between Pacific Islanders who are members of rival youth gangs. But Monday's assault does not appear to have been motivated by gang activity, Shopay said.
