The country's human rights body has absolved prison authorities of having abused Raja Azman Petra, son of fugtive blogger Raja Petra Kamaruddin.

National human rights council, Suhakam, today told reporters that the victim himself had admitted that the injuries were self-inflicted during a fit of temper and there was also no evidence of abuse or wrongdoings committed in the Sungai Buloh prison against him.

"We have conducted a thorough investigation and upon interviewing a few inmates and wardens, it was proven that there are no human rights violations," Suhakam commissioner Siva Subramaniam said.
