MONTPELIER — Working in a stout former bank building with windows closed and air conditioners humming, Orleans County sheriff’s deputies didn’t know what was happening in their parking lot until a neighbor called 911.

A man on a big farm tractor, angry about his recent arrest for resisting arrest and marijuana possession, was rolling across their vehicles — five marked cruisers, one unmarked car and a transport van, according to authorities.

By the time they ran outside, the tractor was down the driveway and out onto the road.

With their vehicles crushed, “We had nothing to pursue him with,” said Chief Deputy Philip Brooks.

Thursday afternoon’s incident ended when city police in Newport, the county seat of the northern Vermont county, caught up with Roger Pion, 34, a short distance away.

No one was injured. At least two deputies had gone inside a few moments before after washing their vehicles, officials said.

“Nobody was hurt. That’s the thing everybody’s got to cherish,” said Sheriff Kirk Martin.

Pion was jailed Thursday for lack of $15,000 bail. He will be arraigned today in Orleans County criminal court on seven felony counts of unlawful mischief, a single felony charge of aggravated assault on a law enforcement officer, as well as misdemeanor charges of unlawful mischief, leaving the scene of an accident, and gross negligent operation of a motor vehicle, according to a statement issued Thursday night by Vermont State Police.

Martin estimated damage to the vehicles at more than $300,000.

Not only were their roofs and hoods caved in, “the radios are ruined, the radar detectors, the cages in the cars ... We’re going to have to get the jaws of life up here to pry the trunks open and see about the rifles and shotguns,” Martin said.

Brooks said the vehicles destroyed constituted more than half the fleet of sheriff’s cruisers in the rural county on the Canadian border. Others were out on patrol at the time of the incident.
