Multiple reports were made last week of a thread on a website sharing intimate photographs of women which had been sent in confidence.
The reports were made last week by complainants in a North Yorkshire town, which The Yorkshire Post is not naming to avoid any identification of those involved.
North Yorkshire Police issued a brief statement on Wednesday, July 8, but has since confirmed that the investigation remains ongoing and that detectives had now spoken to "a number of victims".
A spokesman for the force said on Wednesday: “This is a significant ongoing investigation, and we have now spoken to a number of victims, ensuring they have access to support.”
Details of the offences have not been specified, although the allegations were described by those in the town as "disgusting and disturbing".
Sharing intimate photographs of anyone without their permission, also referred to as 'revenge porn', is an offence under the Sexual Offences Act following a review in 2015 and is punishable by up to two years in prison and a fine.
