A computer engineer who lost £620m-worth of Bitcoin wants to buy the tip where he believes it is buried.

James Howells, from Newport, claimed his ex-girlfriend mistakenly chucked out a hard drive containing 8,000 bitcoins in 2013.

He tried to sue the city council to get access to the site on Newport's Docks Way, or get £495m in compensation, but his case was dismissed by a judge.

Newport Council has been approached for comment.
