Quest for lost hard drive with £4m stored bitcoins
A Newport man has visited a landfill site in south Wales hoping to find a computer hard drive he threw away which is now worth over £4m.
James Howells' hard drive contains 7,500 bitcoins - which is a virtual form of currency for use online. This week, a single bitcoin's value hit $1,000 (£613) for the first time, making his collection worth $7.5m (£4.6m).
BBC correspondent Hywel Griffiths spoke with Mr Howells about what happened.
