A man has been caught on camera pulling a traffic barrier over a level crossing and onto train lines on Lincoln High Street.
The man is shown on video dragging the plastic barrier along the street before leaving it on the tracks at the level crossing shortly after 11pm on May 28.
British Transport Police released the footage as a warning, stating the obvious dangers of obstructing train lines.
PC Helen Green from British Transport Police said: “This was a silly thing to do and, whilst I am confident this wouldn’t have resulted in a serious incident, this man’s behaviour did delay services into Lincoln.
“Please don’t be encouraged by this man’s behaviour, placing items on the tracks is a reckless thing to do and we will not tolerate it.”
Officers are continuing enquiries into the incident and anyone with information should contact British Transport Police by sending a text to 61016 or by calling 0800 40 50 40 quoting reference 727 of May 28.
