Jakarta - The National Police are reviving investigation of several defamation cases against former president Abdurrahman Wahid.

"We have studied all the cases and we think that the public are entitled to legal certainty with regard to the complaints they made to us," spokesman Didi Widayadi told reporters last week.

He denied rumours that the police were seeking revenge against Mr Abdurrahman.

The cases include complaints filed by the former chief of the state news agency Antara, Mr Parni Hadi, following his dismissal, and by the Forestry Ministry's suspended secretary-general Soeripto.
