A vehicle has crashed through a Massachusetts auto auction building, and medics are wheeling people out on gurneys.

The crash occurred Wednesday morning at LynnWay Auto Auction in Billerica (bill-RICK'-uh), about 20 miles (32 kilometers) northwest of Boston.

A witness tells WCVB-TV that cars were lined up on the auction block when one vehicle suddenly accelerated.

Employee Woody Tuttle says he heard tires screeching and saw the vehicle strike several people.

Tuttle told the station: "(The driver) avoided the cars and went on to hit the people who were standing between the cars."

Images from TV helicopters show a vehicle covered in debris that appears to have crashed through an exterior wall from inside the building.

Several ambulances were on the scene, and medics wheeled people out of the building on gurneys.
