A bag containing more than £200,000 worth of jewellery was stolen by thieves who followed a traveller onto a train.
Just before 7pm on December 14, 2023, the victim boarded a train heading towards Edinburgh at Kings Cross railway station, and was followed by a small group.
After the victim put their bag down, two of the group distracted them while another person took the bag and left the train, British Transport Police said.
Investigating BTP officers have released images of people they believe may have information that could help with their investigation.
Anyone who recognises them should contact BTP by texting 61016 or by calling 0800 40 50 40, quoting reference 691 of 14 December 2023.
Alternatively, you can contact Crimestoppers anonymously on 0800 555 111.
