It is not known whether a Cook Islands prison guard will lay a formal complaint with police after being attacked by an unstable inmate.
The Rarotonga prison guard is still off work while recovering from a head injury after being attacked by the male prisoner last week.
The guard was hit over the head with a torch by the prisoner in a reportedly unprovoked attack.
The man's previously served jail terms but is presently on remand facing new charges and is being kept in isolation at the prison.
