A group of teens suspected of breaking into cars was surprised by police near Fairfield Ludlowe High School early Thursday.

An off-duty officer returning home from his shift around 3 a.m. Thursday noticed three teens standing near the corner of Unquowa and Mill Plain roads. When he approached, one of the teens threw away a black object, which turned out to be a TomTom GPS unit, according to the report. As officers were talking to the three, two other teens approached from the other side of the street.

The teens told police they had been playing basketball at the high school, and then were at a party nearby, but were unable to give police the address of the party.

The GPS that had been discarded had a home address of High Street, police said, and the resident there said it may belong to his daughter, who was not home at time.

From four of the five teens, police seized five iPhones, eight gift cards, a Samsung phone, three pairs of headphones and a Fossil watch. Police are investigating the ownership of the equipment.

Police later received a report later of an unlocked car that had been entered on Fairview Avenue. A leather pad and a leather organizer were reported missing, but later found in a neighbor's driveway.
