CHARLOTTE (AP) — Another inmate at a North Carolina prison has stepped forward to say he was beaten while handcuffed.

Randy Massey said he lost a tooth, suffered a cut above his eye and numerous bruises after he hit a guard in March 2015 at the Lumberton Correctional Institution and was taken to a room in the prison to be beaten while restrained.

Massey said the attack started after he admitted to the superintendent that he had assaulted the officer. Then, the superintendent began yelling at him and “gave his officers a direct order to beat me, which they did,” the 53-year-old inmate wrote in a letter to The Charlotte Observer.

Prison officials said they investigated Massey’s case and found no evidence anyone was ordered to beat him. They say he was properly restrained after hitting one guard and attacking another. Massey is serving 62 years behind bars for statutory rape.

Massey wrote the newspaper after a story from May detailed allegations from 65-year-old Morlai Sesay, who said he was hospitalized for four days after being beaten while handcuffed at the same prison in February.

Sesay said guards tripped him and kicked and beat him with batons for no reason as they walked him to a drug test, breaking at least three bones in his head.

State prison spokesman Keith Acree said an investigation into that case found officers were trying to subdue Sesay after he pushed a sergeant, and the prisoner’s injuries happened when he fell to the floor. Investigators ruled there was no inappropriate use of force.

Sesay, who is serving time for breaking and entering, is scheduled to be released in August.

Several other prison employees and inmates shared complaints about organized beatings with The Charlotte Observer, but asked the newspaper not to use their names. Acree said investigators have found no evidence of beatings ordered by prison officials and can’t investigate specific complaints without names.
