Maryland prison officials say several inmates have been stabbed after several fights broke out at the same time at the facility.

Mark Vernarelli, spokesman for the Department of Public Safety and Correctional Services, said the stabbings happened late Friday at the Brockbridge Correctional Facility in Anne Arundel County. The prison houses inmates with two years or less on their sentences.

Seven inmates were taken to hospitals and another was treated at the prison. The spokesman says at least one injury appears to be serious. No correctional officers were hurt.
