Massachusetts driver John Sullivan drives a car into an Asian man in a racially motivated attack

A Massachusetts driver slammed his car into an Asian man — and allegedly drove about 200 yards with him on the hood — in what the victim’s family described as a racially motivated assault.

Driver John Sullivan, 77, went into a rage and shouted “Go back to China” after the victim confronted him for speeding with children nearby, WVCB reported.

The victim was outside the Quincy post office with his sister and their three children just before 11 a.m. Friday morning when they saw Sullivan speeding down the street, according to the WCVB.

Sullivan unleashed a racist tirade after the victim commented on his dangerous driving.

“He said, ‘Go back to China. I’m going to the post office and I’ll be out in five minutes. If you’re still here, I’ll kill you all,'” said Desiree Thien, the victim’s sister.

Thien and her brother stayed in front of Sullivan’s vehicle and gathered his information before he came out and got into his car.

“He rammed my brother. My brother rolled onto the hood and he clung to the hood. He drove a good 200 meters, then he braked so that my brother fell,” said Thien. “As (my brother) tried to keep his balance, he hit my brother again and continued his racial slurs.”

Quincy Police said Thien’s brother was thrown into a 10- to 15-foot-deep ditch at a construction site. Sullivan fled the scene.

A witness followed Sullivan and informed police of his whereabouts, which was then passed on to the police department in neighboring Braintree, where he was arrested.

“He needs to know that not everyone can be teased and not everyone can be silenced through intimidation,” Thien said.

Sullivan is charged with double assault and battery with a dangerous weapon, reckless operation of a motor vehicle, leaving the scene causing personal injury and a civil rights violation, according to the WCVB.

He pleaded not guilty to his arraignment in Quincy Circuit Court on Friday, according to the Norfolk Attorney’s Office.

He is being held without bail pending a dangerousness hearing scheduled for Wednesday.
