Nine Network reported last week a woman claimed that she suffered injuries during a sexual encounter with Hayne in the NSW Hunter Valley and that she had photographs to back up her story.
He is also not to assault, molest, harass, threaten or otherwise interfere with the victim, stalk or engage in any other conduct that intimidates the victim or a person with whom the victim has a domestic relationship.
"Hayne is being interviewed at the Ryde police station by detectives from the sex crimes squad", Wielder said.
An investigation into the incident was launched after the woman was interviewed by the NRL Integrity Unit, and the matter was passed on to police.
The woman did not go directly to police but took her complaint to rugby league bosses earlier this month.
He did not say a word, despite being asked several times whether he would be fighting a charge of aggravated sexual assault.
Hayne is also defending a civil case in the United States over a woman's accusations that he raped her during his time as a San Francisco 49ers National Football League player.
Hayne's representative Wayne Beavis opted not to comment when contacted by AAP after the allegations arose.
The woman, identified only as JV, reports the incident to police, but prosecutors refuse to charge Hayne because of insufficient evidence.
Hayne is also facing a civil suit in the United States, after being accused of rape.
The former Parramatta Eels footballer presented himself at Ryde police station at around 4pm on Monday afternoon where he was in the process of being charged over the alleged assault.
