Police are hunting a man who allegedly tampered with three trains causing commuters from London to fail to get off at their stop.
British Transport Police (BTP) claimed the suspect boarded a train at Marylebone and began to tamper with it, stopping the doors from opening as it pulled into Bicester Village.
He then boarded a train to Banbury and interfered with the same part of the train during his journey of destruction on November 9.
The man then caught a service to Solihull and tampered with a different part of the train causing the service to break down.
BTP officers believe the man in the CCTV images may have information which could help their investigation.
