At 5:45pm on Saturday 9 April, a man and woman boarded a train at York station that traveled directly to Kings Cross.
When the train attendant told them that the service didn’t stop anywhere in between, they became abusive and demanded to get off the train. They cursed her and threatened her with violence.
The train then stopped unscheduled at Retford station, where the couple got off and left the station.
