A suitcase containing 1 million pounds worth of gems was stolen from a luggage rack on a train at London’s Euston Station, and British police have been hunting for an unidentified man following the theft.

Thirty-five-year-old jewellery dealer and owner of the gems boarded the train to Birmingham but when the train arrived at Rugby in central England, he discovered that his suitcase of rubies, emeralds and sapphires was no longer on the luggage rack.

The police has released a grainy image of a man who they said they would like to speak to.
