When she came to leave the train at Wymondham she discovered her bag had been taken.

PC Tony Orton, investigating officer, said: “Following the incident, we have carried out a number of enquiries including speaking to witnesses on board the train and viewing CCTV from the station and the surrounding area.

“We believe the bag was taken by a woman who left the train at Ely station. After reviewing CCTV, we have since isolated images of a woman that we are keen to speak to.”

The appeal follows the launch of Operation Magnum earlier this year, a campaign to help rail passengers keep valuables safe from pickpockets, gadget-grabbers and luggage thieves.

As part of the initiative, officers have issued video clips to help the travelling public spot the most common tricks thieves use.

Operation Magnum involves British Transport Police working with train operators and local police forces to disrupt and deter pickpockets who prey on unsuspecting commuters and tourists at busy stations.

It also targets thieves who brazenly snatch expensive smartphones from distracted passengers’ hands and those who steal luggage and valuables on trains.

Videos featured on the Op Magnum website (www.btp.police.uk/theft) and the BTP YouTube channel show passengers the 13 most common tricks thieves use, while anti-theft surgeries give advice on how to protect yourself from thieves.

Anyone with information about the Ely incident should contact British Transport Police on 0800 40 50 40 quoting background reference B12/LNA of 08/10/2013.

Information can also be passed to the independent charity Crimestoppers on 0800 555 111.
