Reports of online blackmail incidents involving users of an adult escort website are being investigated in Northern Ireland.
Information received so far, by detectives in Antrim, has been from men who accessed a local escort website.
It is understood that after talking or texting with a woman, the men are then threatened that if they do not pay money, details of their contact will be disclosed to their friends and family.
A 31-year-old woman has been arrested on suspicion of five counts of blackmail.
She is currently on police bail pending further enquiries.
The PSNI believe there are more victims who have not contacted police due to the sensitive or embarrassing nature of the incidents and detectives are appealing for them to contact police now.
They are urging anyone with information to come forward and assured people that their information will be treated in confidence.
