LANCASTER, Mass. (WHDH) -- Three brothers were arrested after police said they drove away from a traffic stop, dragging an officer along the way.

The chase came to a crashing conclusion at a telephone pole at the intersection of routes 117 and 70.

“I didn’t drag any cop down the road. I know that for a fact,” said Shaun Leary, suspect.

Shaun Leary and his two brothers were released on bail from Lancaster police headquarters after they were arrested following a police chase hours earlier -- with speeds reaching in excess of 80 mph. It ended when the suspects’ car crashed into a telephone pole.

“It was scary when you see the policeman get his rifle out of the car and go after the kid,” said Cathy Quinn, a witness.

The traffic stop began with the driver, Shaun Leary, dragging a Lancaster detective 60 feet before the detective broke free, escaping with bumps and bruises.

“So as the car is taking off the window is coming forward and catches the officer’s arm and as soon as it begins to drag you go off balance. Now you’re trying to play catch up and the car’s speeding away,” said Sgt. Ed Burgwinkel, Lancaster Police Department.

With the three suspects in custody, police discovered over one pound of marijuana and more than $1,000 in cash.

“Yeah, that’s true [they found a pound of marijuana in my car],” Shaun Leary said.

Back at the scene of the crash, one of the suspects, Dylan Leary, and a woman, Kyra Thompson, returned.

“[I bought the marijuana] for me to smoke,” Dylan Leary said.

Police were dispatched back to the scene where Dylan Leary was arrested again and Thompson was as well after police found drugs at the scene -- including oxycodone and heroin.

“Those types of situations can lead to terrible events taking place,” said Sgt. Ed Burgwinkel.

Dylan Leary is being held without bail and will appear in Clinton District Court on Wednesday. His two brothers are out on bail and will appear in court on Friday.
