The New South Wales Parole Authority has delayed its decision on whether to release a convicted gang rapist from jail, after hearing police evidence the man's family is linked to the Brothers For Life criminal gang.

Mohamed Sanoussi has served 13 years of a 16-year prison sentence for the gang rape of several girls in 2000, when he was 16.

The now 29-year-old has already had applications to be released on parole rejected three times, though he has been granted weekend leave since October last year.

Today Sanoussi again faced the Parole Authority, where it was widely expected he would be released within weeks, subject to extensive electronic monitoring.

But the Corrective Services Commissioner's lawyer, Geoffrey Denman, told the hearing the Middle Eastern Organised Crime Squad alleges that Sanoussi's family is connected to the Brothers For Life gang and that his release presents an unacceptable danger.

Sanoussi's lawyer, Ruth Layton, told the Parole Authority that is not the case.

"He's addressed his offending behaviour. He's grown up in jail," she told the hearing.

The Parole Board has reserved its decision.
