Vandals struck the All-Star Transportation bus terminal on Dodd Road in New Milford over the weekend, slashing 93 tires on 45 school buses.

Damage was estimated at more than $30,000, said police, who are conducting an investigation into the crime.

The perpetrators are facing one year in prison on a "significant charge of criminal mischief," said Lt. Larry Ash.

New Milford schools were delayed two hours Monday morning, while bus terminal manager Jeff Woods found alternate buses.

Buses were brought in from Washington, Sherman, Brookfield, Ansonia, Prospect and Seymour to transport students.

Preschool and morning kindergarten classes were also canceled, according to the school district's website.

Superintendent of Schools JeanAnne Paddyfote said she received a call Monday morning from Mr. Woods.

"Because the call was coming late, he said I should delay school today," Dr. Paddyfote said. "He said `I don't have enough buses to do the run on time. I need two hours ... I'm trying to get buses from other locations. ...' "

Mr. Woods said the vandalized buses represented a "good part of the fleet." All-Star keeps 72 buses at the Dodd Road site.

"Local dealers are stepping up and sending over what tires they have," Mr. Woods said. "We're getting tires replaced on the buses as soon as the trucks come in."

Anyone with information about the incident is asked to contact the New Milford police at 860-355-3133.
