THE PSNI in Derry have urged people not to share intimate images and videos of themselves online.
It comes after reports relating to a man who has threatened to send them to their family and friends.
Police are investigating several reports from women befriended via social media and later threatened if they refuse to send more images.
Police Derry City and Strabane say on their Facebook page: “This is one we really want you to share.
“Making new friends or potentially finding a new relationship online is pretty commonplace these days but there are some people out there who use this as an opportunity to cause harm.
“We have a number of reports from women who have been befriended through Facebook or Snapchat and over time the conversation has moved to the sharing of intimate images or videos.
“This male has asked these women to meet up in person or share further images and when they decline he threatens to share the images and videos with family and friends.
“This person uses a variety of names and becomes extremely persistent and aggressive when the women try to cut off contact.
“We are investigating all the reports that have been made to us and would ask that you please think twice about sharing intimate images online.
“You will have no control over where they go or who can see them.
“If you have found yourself in this position please speak to us – we can help.
“Ring us on 101 or report online via www.psni.police.uk/makeareport
