ROCKLAND – Two people suffered non-life-threatening injures when a car backed across Union Street and into a storefront, a fire official said.

Lt. John Sammon of the Rockland Fire Department said the accident occurred at about 6 p.m. at Rockland Athletic Supplies, 320 Union St.

The car was in the parking lot of a shopping center across the street from the store and backed up across the lot and across Union Street before striking the front of the building, he said.

“There’s extensive damage to the front of the building,” Sammon said.

The car’s driver and a passenger were injured. They were taken by ambulance to Brockton Hospital, Sammon said. No one in the store was injured, he said.

The cause of the accident is under investigation by Rockland police, Sammon said.
