A South Korean married couple have been arrested for using a sex tape to blackmail their former college classmate and taking over 158 million KRW (S$190,000) worth of money and valuables from her.
According to Allkpop, the two 32-year-olds had secretly filmed their former classmate having sex and held onto the sex tape.
They then threatened to expose it unless she gave them money and valuables.
The husband took around 90 million KRW worth of items from her and his wife had taken an additional 68 million KRW from their now former friend.
The police believe that the two had conspired for some time to secretly install these cameras and cheat their victim of her possessions.
