Who is Nicholas Alahverdian?

The story came to Scotland last Christmas when a man was arrested at the Queen Elizabeth University Hospital in Glasgow. He said he was Arthur Knight, but the American authorities were certain he was Nicholas Rossi, wanted for raping a 21-year-old woman in Utah in 2008, and other sex attacks. A judge in Edinburgh has now rejected his claims of mistaken identity, ruling that he is Rossi, and extradition proceedings will follow.
