BOSTON (TNND) — At least six people were injured Tuesday when a box truck crashed into a building in Boston's Chinatown neighborhood, according to police and emergency services.

Four people were taken to the hospital, including two in critical condition and two others treated at the scene, Boston EMS said.

The Boston Fire Department shared photos of a yellow Penske truck flipped on its side and wedged between a pole and a building. Firefighters used extrication tools to remove the trapped driver from the cab of the truck.

Boston police did not provide the driver's name or the circumstances that led to the accident.

Penske spokesman Randolph Ryerson told The Associated Press it was “aware of the incident” and was monitoring it closely.

"Penske will be cooperating fully with authorities to support their investigation,” Ryerson said. "Our thoughts are with those who have been injured in this unfortunate incident. Based on our records, the truck involved was out on rent to a commercial trucking company. We have no other information at this time."
