Parramatta believe they have identified the culprits who racially taunted Petero Civoniceva and say they should banned for life unless they apologise to the Penrith captain.

Eels officials had been investigating the incident in which monkey chants were allegedly aimed at the Fijian-born Civoniceva in Sunday's 22-16 NRL win to the Panthers at Parramatta Stadium.

After viewing footage of the crowd supplied by Channel Nine and several witness statements, Eels officials Tuesday passed on the details of two "persons of interest" to NSW Police.

"We think we have a name and address for the culprits and I've passed that on to the police who are considering their next step," Parramatta chief executive Dennis Fitzgerald said.

Once police have investigated the matter and if the suspects are found to be the perpetrators, the club will work with the NRL to determine an appropriate penalty.

Fitzgerald insisted the pair should apologise to Civoniceva and said failing to do so should result in a life ban from all NRL matches.

"If they don't apologise there will be no reason for us to let them back in at all and I'm sure that the NRL would agree with that," Fitzgerald said.

"They would be banned from all games until such times as they show some contrition but if they don't it will just stay a ban indefinitely.

"The police will contact these people and give them an opportunity to say something, then we can go from there and have a meeting with the NRL."

NRL chief operating officer Graham Annesley said the league would await the police findings but paid tribute to all parties for dealing with the matter quickly.

"I think they've made fantastic progress, the stadium and the Eels and it's all looking quite promising," Annesley said.

"To have gone as far as what we have so far is pretty good progress."

Civoniceva, one of the most respected figures in the game, has been given four days off by Penrith after also starring for Queensland in last Wednesday's State of Origin decider.

He took the extraordinary step on Monday of issuing an apology to Eels officials and fans after beer was spilt when he reacted to the taunts by hitting the fence at the stadium near the offenders.

Fans and players have come out in support for Civoniceva, believing the Test hardman was well within his rights to react to the taunts.

"He's got every right to be upset with those sort of comments," Parramatta winger Jarryd Hayne said.

"It is surprising and sort of upsetting.

"I'm not too sure who said it, whether they were people that turn up every week or not ... but further action needs to happen.

"We have a great fan base here and this comes back on Parramatta's name."

The incident has also upset officials in Fiji.

"It is sad that racism is still well and alive today," Fiji National Rugby League chairman Peni Musunamasi said.

"We cannot begin to imagine what Petero is going through right now, he is very shy but humble and only loves to play.

"I think it's pretty disgusting really, for people to resort that low.

"Drunk or sober, no one should be called names and racially abused because of the colour of their skin, those days are long gone."
