Boston-- A deputy sheriff and a prisoner were shot at a Boston hospital Wednesday, the police said.
Boston police said the prisoner is in custody.
Boston Police Commissioner Ed Davis said two deputy sheriffs brought a prisoner in for treatment at Massachusetts Eye and Ear Infirmary, CBS Boston station WBZ-TV reports.
"As the handcuffs were being taken off the suspect, he began to struggle for the gun, there was a fight," Davis told reporters outside the hospital.
"He began to struggle for one of the deputy sheriff's guns. The two individuals fell to the floor, a round was fired and one of the deputy sheriffs suffered a gunshot wound to the leg."
Police say the deputy sheriff was in serious condition but expected to be OK.
The second deputy sheriff shot the prisoner in the chest in response and he was critically wounded, according to Davis. He was rushed to nearby Massachusetts General Hospital. His name has not been released.
Police have shut down the area around the two hospitals.
The hospital is open but the Emergency Department is currently closed while police investigate the shooting.
