Parramatta star Semi Radradra has been detained by police and is assisting them with inquiries in relation to an allegation of domestic violence.
The winger, was put into an unmarked car by police at Sydney International Airport's loading dock just before 11pm (AEST)on Thursday, after he returned on a flight from Fiji.
"A 24 year-old man has been detained by police at Sydney Airport tonight," a NSW Police media spokesperson said.
"He has been taken to Mascot police station, where he is assisting police with inquiries in relation to domestic violence."
The winger returned to Australia to face battles on various fronts, his former partner having sought an apprehended violence order against him following allegations of multiple assaults.
There was also confusion about his playing future with reports the flyer was seeking a release from his NRL contract to play in France and may be considering a switch to rugby union.
Hayne's manager was at the airport but no Parramatta official was spotted.
Former Eels teammate Jarryd Hayne was left to do the talking, the ex-Eel sharing the flight with Radradra from Nadi.
He said Radradra have told him he was returning to play for Parramatta and described him as the Eels marquee player.
"I'm more worried about the person himself than the athlete, I think thats the most important thing," Hayne said before the news of Radradra being detained was confirmed.
Asked about how Radradra had reacted to the developments of the last 48 hours when details of the AVO became public knowledge, Hayne said: "It has been a bit of mayhem by all reports but I think the biggest advice I gave to him is he's got to run a tight ship." .
The NFL convert, who is now seeking a start for Fiji in rugby sevens at the Rio Olympics, said it was just a coincidence that the pair were on the same flight.
"Thats why I put that tweet out "God be up to something,'" Hayne said.
"It was good to spend time with Semi and I hadn't been able to catch up with him due to our training program and being a bit away from Suva as well.
"So it was great just to sit at the airport and have a conversation with him and just try to help him out as much as I can and (offer) as much advice as I can give him."
Radradra was expected to train with Parramatta on Friday morning and play against Cronulla on Saturday prior to be detained by police.
Hayne has returned from Fiji for treatment on a hip injury in a bid to remain in contention for their sevens Olympic team to be named in two weeks.
He said he has strained quadriceps on Tuesday and was looking to see his chiropractor on Thursday and may need scans.
