Victims have been tricked into taking their clothes on camera in exchange for cash prizes on a hoax ‘nude game show’.
Two men have reported being invited to a hotel to take part in naked ‘challenges’ in return for the chance to win £5,000.
Now Scotland Yard detectives believe there may be more victims in relation to these events, which are thought to have taken place from 2013 onwards.
Anyone who could have fallen prey to the scam is being urged to come forward.
One victim, 28, told police he was approached by a 29-year-old man who claimed to work in the entertainment industry.
He was asked to go to a hotel in Newham, east London, to take part in several nude challenges in June 2018.
The suspect is said to have kept the footage for his own gratification, the Metropolitan Police said.
Another man, 31, reported in February this year how he had been coerced into similar activities at a hotel in south-east London in August 2013.
A suspect was arrested in January last year on suspicion of voyeurism and released under investigation.
Sergeant James Mason, of the Met’s North East Basic Command Unit, said: ‘We believe there may be more victims in relation to these events.
‘I urge anyone who may be a victim of similar crimes or incidents from 2013 to the present day, to come forward with information.
‘The reported incidents took place several years ago and it is important we are able to investigate these and support any further victims.’
