The incident occurred at a property in south Belfast on 28 June.
Ulster duo Paddy Jackson and Stuart Olding are two of three men that have been arrested by the PSNI in relation to a number of alleged sexual offences reported to have taken place at a property in south Belfast on 28 June.
The BBC have reported that both men were interviewed by the police and then released from custody.
Fly-half Jackson was not included in Ireland’s 27-man squad to face New Zealand this Saturday in Chicago due to “personal reasons”, according to the IRFU official statement.
The PSNI have confirmed in a statement that a file will be prepared for submission to the Public Prosecution Service.
