Police are hunting for a woman who allegedly sexually assaulted a male train worker as he walked through a carriage late at night.
At the time of the assault, the railway employee had been passing through a carriage as it travelled between Sutton Parkway and Shirebrook in northern Nottinghamshire.
The attack is said to have occurred at around 9pm on Saturday, May 31.
Now, the British Transport Police have issued an urgent appeal for the public's assistance and are hoping to speak to a woman captured on CCTV on the day of the incident.
Officers believe that she could hold vital information that could help aid their investigation.
