Six prison guards have been stabbed and left with broken bones after being attacked by 20 inmates in a recreational yard.
The guards and two of the inmates were hospitalized following the incident.
The correctional officers at Richard J. Donovan Correctional Facility in San Diego were set upon by the inmates at around 4pm on Sunday afternoon.
About 20 inmates were in the recreation yard when some began the attack on the correctional officers, a press release stated.
Officers ordered the inmates to stop and used ‘less-lethal methods’ to attempt to quell the violence.
One of the guards then fired a warning shot into the air which stopped the attack.
The guards sustained stab wounds, lacerations and possible broken bones in the incident, according to California Department of Corrections and Rehabilitation spokesperson Terri Hardy.
They were taken to a nearby hospital. There condition was not immediately known.
Two of the inmates were also hospitalized. Other inmates involved were taken to the prison’s medical facility for treatment.
The extent of their injuries wasn’t released. It was unclear how many inmates were hurt.
According to Hardy, several weapons were recovered from the inmates.
The prison’s Investigative Services Unit was looking into the incident, including working to determine how many inmates were involved in the attack, Hardy said.
They could face charges of attempted murder of a peace officer.
The prison houses 3,600 minimum-, medium-, and maximum-security inmates.
