Three men have voluntarily gone to PSNI stations for questioning about an ongoing investigation into historical abuse in County Down, police have said.
None of the three were arrested but all have been reported to the Public Prosecution Service.
Thirteen other people have previously been arrested as part of the inquiry.
One woman and three men were charged and have appeared in court while all the others were released either on bail or pending reports to the PPS.
Of the three men who went to police stations recently, one was interviewed last Wednesday in relation to an allegation of harassment and an offence under the Telecommunication Act 1984.
A second was interviewed on Saturday in relation to two allegations of child sexual abuse.
The third man was questioned the next day in relation to an allegation of indecent assault on a child.
