A hit-and-run driver who sent a seven-year-old Duxbury boy to the hospital with serious injuries is still at large, say Braintree Police.

The boy was severely injured last Saturday during a hit and run accident in Braintree. The boy was playing in the yard at a relative’s graduation party on Richard Road when he chased a ball into the street, according to police.

He was then hit by a car and run over by the back tires, according to a police press release. The boy is being treated at South Shore Hospital for a fractured right tibia and a fracture to his pelvis.

His name has not been released and no further updates on his status were available as of press time.

The boy described the vehicle as a brand new black car, that looked like a police car without lights. He added that it might have had a BMW logo on the back, said police.

According to the report, no adults witnessed the accident, but other children at the party (ages five and six) saw the vehicle and said that it had a brown top.

The police are unsure if the operator of the vehicle realized that he had hit the boy. There have been no further updates on the case as of Monday, Russell Jenkins, Braintree deputy chief said. The driver of the car has not come forward or been identified, he said.
