Police are looking for this man (Picture: Handout)

There’s no doubt that train journeys can be painfully dull.

But while most travellers will peruse their phone or read a book, one man apparently decided to pass the time in a rather more socially unacceptable way.

Police are appealing for help finding an alleged mystery masturbator on a train near Blackfriars station who was seen in a video posted to social media.

‘We have been made aware of a video posted online that appears to show a man touching himself inappropriately,’ said Detective Sergeant Margaret Storey.

‘Officers are currently analysing the video, and are appealing for the person who recorded it to come forward.

‘I believe that the man in the photo can help us with our investigation, and would urge him to make himself know to us, or anyone who knows him to contact us.’

It is unknown when the incident happened or at what time.

Anyone with information is asked to contact police on 0800 40 50 40 or text 61016, quoting reference ESUB/B4 of 24/02/15.
