Humberside Police have seen a big increase in sextortion crimes over the past five years, new figures reveal.
In 2016/17, the force recorded 39 sextortion crimes, where criminals persuade a victim to perform sexual acts in front of webcam or share explicit material before threatening to send the pictures or video to friends and family or post it online if money is not paid.
This was up from just four recorded in 2012/13.
The number of reports rose 44 per cent in just a year, from 27 in 2015/16.
One victim, who was aged under 16, in 2014/15 was asked for £3,500 after they were encouraged to post a video of themselves naked on a Facebook chat.
Another was asked for £25,000
