gem theft
Polcie believe this man may have information which could help the investigation BTP

Police have launched an appeal after a suitcase containing more than £1m worth of gems were stolen from a train at London's Euston station.

The suitcase was stolen after the victim, a 35-year-old jewellery dealer, boarded the 7.03pm train to Birmingham New Street on 8 November.

Once he boarded the train, he placed the suitcase on the luggage rack and only realised it was gone when he arrived in Rugby.

Police believe the suitcase was most likely stolen from the train before it left the station at Euston.

The stolen bag contained more than 40 high value gems including rubies, emeralds and sapphires worth more than £1m in total.

Police have now released CCTV footage of the man they wish to speak to in connection with the theft as they believe he may have information which could help the investigation.

Investigating officer, Det Sgt Nick Thompson from British Transport Police, said: "I would like to speak to the man in the CCTV images about this extremely high value luggage theft.

"I'd also like to hear from anyone who was on board the train or at Euston station on Wednesday evening, who may have seen a man acting suspiciously.

"The suitcase was a large black suitcase and contained more than 40 gems such as rubies, emeralds and sapphires."

If anyone has any information about the incident or recognises the man shown in the CCTV images, please call BTP on 0800 40 50 40 or text 61016, quoting reference number 529 8/11/17.
