WEST Midlands police are appealing for information after three trains were tampered with.
On 9 November a man boarded a train at Marylebone and began to tamper with it, which led to the doors not being able to open as it arrived at Bicester Village and passengers not being able to alight.
He then boarded a train to Banbury and interfered with the same part of the train on this service.
The man then boarded a train from Banbury to Solihull and tampered with another area of the train which caused the service to break down.
Officers believe the man in the CCTV images may have information which could help their investigation.
