The PSNI said is it receiving continuing reports of such incidents in the area, which are soon following by demands of money.
Clonoe schoolboy Ronan Hughes tragically took his own life last year after falling victim to such a scam online.
Blackmailers had threatened to post pictures of him on the internet unless he paid them £3,000.
In a post on Facebook this morning, police said: “Police in Mid Ulster continue to receive reports of incidents where victims are approached on Facebook by unknown females requesting intimate videos.
“Demands for money from their victims then follow.
“We are committed to fully investigating this type of crime when it is reported to us, however, we want to do all we can to raise awareness so this doesn’t happen at all.
