Where is the Cryptoqueen?
When a plush London penthouse flat bought by the "missing cryptoqueen" Ruja Ignatova re-appeared on the market, it appeared the fugitive scammer was orchestrating a sale from the shadows.
The same week her £12.5m "ultimate penthouse" was listed for sale, new UK transparency rules meant Ms Ignatova was also publicly revealed as the owner.
But the OneCoin fake cryptocurrency founder hasn't been seen for five years and currently sits on the FBI's 10 most-wanted list.
The BBC previously revealed
how she secretly bought the four-bedroom penthouse, said to have once been stuffed full of expensive artwork and designer clothes, after financial regulators in at least one European country had already issued a warning about her fake cryptocurrency.
Ms Ignatova, a 42-year-old Bulgaria-born German national, disappeared on 25 October 2017 after being tipped-off about intensifying police investigations into her Sofia-based scam.
OneCoin, created in 2014, is one of the biggest known of such scams, with the FBI estimating its value at $4bn (£3.2bn).
In the UK alone, the BBC estimates that investors lost more than £100m.
Layla Begum, from Bow, east London, says her family lost more than £54,000 in OneCoin when she was persuaded to invest by a family friend.
