Cumbria police are issuing advice on what to do if a person believes they're a victim of sextortion.
It comes after officers received four reports of the crime over the weekend.
Sextortion is a cyber-enabled crime in which a victim is lured into performing sexual acts in front of a webcam. Unbeknown to the victim, their acts are being recorded and the criminal will then use the footage to blackmail them.
Offenders can be based in any part of the world even though they may appear to be local.
Anyone who feels they may be victim of sextortion are asked to call police on 101.
