One of the men involved in the incident was stabbed, but sources with knowledge of the incident say that Fainu was not responsible. Charges have not been laid but the 21-year-old is a person of interest to police.

Fainu sought to speak to police over the weekend, although police were not available to process him at the time.

He has engaged high-profile lawyer Elias Tabchouri, who represented him when he avoided conviction after pleading guilty to filming a sex act without consent, to again represent him even though no charges have been laid.

"Mr Fainu has again retained me and arrangements are being made to hand himself in to police to allow these matters to be processed," Tabchouri told the Herald.

"Mr Fainu had previously sought to hand himself in to police but unfortunately police were not available on the day.
