The mysterious prowler of Bank Street struck again late Saturday night, his fifth attack on student cars this semester, according to the mechanic at Art Trump's garage. Other garages reported that they had been called to repair damaged cars on Bank Street at least once or twice this spring.

Last night the police were still without any clues to the identity of this attacker, whose methods have formed a persistent pattern. He either lets the air out of all four tires, or pierces each of them with a razor-sharp, pointed instrument, like a filed ice-pick. As a final artistic gesture, the windshield wipers on most of the cars have been twisted back in an arc.

Surprisingly enough, the past-midnight phantom has not tampered with any of the aerials. A spokesman at the Police Department stated that the usual vandals almost invariably pull a car's aerial off as the initial gesture.

The most unusual feature about these attacks is that the victimized cars have been parked in approximately the same place. The chief danger spot is by the large tree--about three houses down--on the right hand of the street, coming off of Mt. Auburn St.

The chief mechanic at a Memorial Drive garage had two theories about the attacks. "It's probably a guy who lives in that house by the tree," he stated. "But there's something strange about these jobs," he added. "They always come in two's, around the nights of a full moon. It doesn't seem natural."
