BOW, N.H. (AP) – Police are trying to find the people who slashed tires on at least four police cruisers as officers were in the woods investigating an underage drinking party this week.

Bow police Lt. Dave Girard said officers were checking suspicious cars on a country road late Monday, when several teens emerged from the woods. Police concluded an underage drinking party was going on, so officers from Bow, Henniker, Hopkinton and the state police went into the woods to investigate.

When the officers returned to their cruisers, they noticed their tires had been slashed.

Girard said at least one tire on each cruiser was slashed, meaning someone who originally might have faced a misdeamonor fine for underage drinking, now could face prison time for a felony.

They arrested two teens on drug, alcohol or drunken driving charges and are looking for the vandal or vandals.
