FRYEBURG – An Oxford woman was charged with possessing a butterfly knife, which a policeman described as one of the deadly fighting weapons seen in martial arts movies.

Sgt. Michael McAllister said Fryeburg police arrested Mandy Ann Files, 22, of Oxford on Saturday night after she gave a false name to an officer and then found to have allegedly stashed the illegal knife under a car seat.

Files was charged with failure to give correct name and trafficking in dangerous knives. She was released on $500 unsecured bail pending her court appearance and ordered not to possess any weapons.

Officer Michael Hall approached a car parked in a field off Lovewell Pond Road in Fryeburg prior to the arrest. Hall realized that Files gave him a false name when he discovered her purse inside the car with correct identification in it.

Files was a passenger in the car with Alan Edwards, 29, McAllister said.

McAllister said butterfly knives are illegal in Maine, but that people might be able to order them in mail-order catalogs.

McAllister said he did not know where Files bought her knife.
