A police investigation has begun into claims that a prisoner was raped by his cellmate while locked in overnight at a privately run men's prison in South Auckland.
The Department of Corrections has also launched its own inquiry into the attack at Auckland South Corrections Facility.
As well, the assault was receiving political attention - a spokeswoman for Corrections Minister Peseta Sam Lotu-Iiga said last night he had been told of it and had sought more information.
A family member of the inmate told the Weekend Herald he rang on Wednesday saying: "I'm scared. They're putting me in mainstream and they're not giving me a reason."
Until then, the inmate had served almost half his sentence in segregation.
