Overview

• Shortly after the 7pm departure from Glasgow Queen Street on June 8, a woman was seen performing a sex act on a man aboard the ScotRail service to Edinburgh.
• A train guard halted the act during routine rear-carriage checks, triggering a British Transport Police investigation.
• Detectives have now identified the man as a white male in his late 30s with facial tattoos and a greying beard and the woman as a white woman in her 30s with blonde hair.
• Officers cite incident 554 of 8 June in urging witnesses to call BTP on 0800 40 50 40 or text 61016, or to provide anonymous information via Crimestoppers.
• The appeal underscores enforcement of public decency laws on UK rail networks and the reliance on bystander evidence to strengthen prosecutions.
