The threat was first sent to Bannatyne at the end of July. It read: "We are the men of Belarus. We do not give up. We will stand tall. Give us £35,000. Expect us."
This followed with a set of instructions from the blackmailer, nickname @YuriVasilev_: "Dear Dragon, My name is Yuri Vasilyev and I'm looking for a £35,000 investment to stop us hurting your Hollie Bannatyne. We will bring hurt and pain into your life. We are watching her. She is very attractive. Want photos? Tweet using the hashtag #4money to confirm payment will be made."
Bannatyne has managed to narrow down the location of the anonymous user to Moscow but now seeks the help of the digital community to scout out the individual himself.
"I offer £25,000 reward for the capture of the coward who calls himself Yuri Vasilyev," Bannatyne tweeted earlier today. "Double if his arms are broken."
Bannatyne later raised the stakes: "OK £30,000 reward for info leading to his arrest."
So far, there has been overwhelming support from across the Twitter community:
This does not look like a hacking attempt on Bannatyne's account - although nothing can be ruled out at this early stage. If the posts are all real, this is citizen journalism meets vigilante justice live and in colour.
