A spokesperson for Serco, which runs the facility, said a prisoner was assaulted by another inmate earlier today.
“Our staff acted immediately to protect the victim and restrain the assailant.
“Hato Hone St John was called immediately, and the prisoner was transferred to hospital in a stable condition. The incident was also reported to the police, who attended the site.”
Assaults in prison are illegal, unacceptable and would not be tolerated, the spokesperson said.
