Con-men are dressing up as women, posing with fake breasts and prosthetics to fool men on live chats to hand over their money.
Devious fraudsters in China have been tricking unsuspecting targets into exposing themselves on camera - and then allegedly blackmailing them for huge sums of money.
According to reports, the bizarre trend has been sweeping across China over the past year, with male scammers taking part in live nude chats.
After being convinced to take part, victims then discover their naked bodies have been filmed, as the scammers go on to demand payment.
Following recent attempts, police in China have issued an official warning to men, urging them to be more vigilant when using online chat rooms and forums.
Officers even published a video on the Chinese social media network Weibo, with a very simple message.
It read: "Boys, don't chat nude."
In the video, the police explain how these con-artists use prosthetics and women's clothes to fool them into getting their kit off on camera - showing just how realistic these criminals can look.
One of the officers is pictured wearing a bra and underwear before pulling the fake skin away, revealing his male chest underneath.
The video then cuts to footage of two men holding up sets of 'fake skin' disguises.
All this goes on while a female police officer can be heard saying: "You think what you think is what you think?"
The officer then urges caution, adding: "Boys, don't chat nude. It's fraud."
The video was originally posted in the eastern Zhejiang province, but has since been shared by police social accounts across the country.
According to reports, these organised criminal gangs spend weeks grooming their victims before encouraging them to take off their clothes.
They do this by getting them to download what, on the face of it, appears to be an ordinary video chat app, but is actually spyware designed to scan their phone and email contacts.
The crime has become increasingly prevalent during the coronavirus pandemic.
In the first six months of 2020, The Guangdong Public Security Department received over 9,000 complaints of blackmail relating to these so-called 'nude chats'.
According to police, a least 10 separate blackmail gangs have been also identified, with some 86 offenders having been arrested as a result.
Over 2,000 victims have been identified and over £2 million has been extorted by the crooks.
