At 5,45pm on Saturday 9 April, a man and a woman boarded a train at York station travelling directly to Kings Cross.

When told by the train guard that the service wasn’t stopping anywhere in between, they became abusive and demanded to get off the train. They swore at her and threatened her with violence.

The train then made an unscheduled stop at Retford station, where the couple disembarked and left the station.
