Police are advising people to be cautious on dating apps after a North Fulton man was scammed out of nearly $4,000 by a woman he met online, Channel 2 Action News reported.

Alpharetta police said the man, who was not identified, started chatting with a woman he believed lived in the Philippines on the dating app called “Viber.”

Things seemed to be going well and at some point, the man sent the woman explicit photos of himself, Alpharetta police spokesman Sgt. Howard Miller said.

That’s when things took a strange turn.

“The woman on the other end then started to demand money and threatened our victim with showing his naked pictures on Facebook and other social media,” Miller said.

Eventually, the man forked over nearly $4,000 to avoid having the photos made public, authorities said.

“Our advice is to just be cautions when you’re dealing with people on the internet because you really don’t know who you’re talking to and you don’t know what their motivations are,” Miller said.

The cash was sent through Western Union, so investigators hope to track it to a bank account in the Philippines, but the chance of recovering the money isn’t likely.
