FARMINGTON, Minn. (AP) — Farmington police say a homecoming stunt was dangerous — and potentially criminal.

There's an unofficial tradition at Farmington High School of homecoming pranks between the senior and junior class. But Police Chief Brian Lindquist says it went too far this time. Several seniors commandeered four juniors and took them for a "joy ride" Sept. 27. The seniors zip-tied the hands of two of them behind their back and put them in the trunk.

Police became aware when the car got into a fender-bender. Nobody was injured, but the police chief says he hopes the threat of charges sends a strong message.

The Dakota County attorney's office is reviewing the case. Some of the 17 students involved are adults, so the legal consequences could be more serious for them.
