Police have released an image of a person they want to speak with after a man was seen hitting a child on-board a train.

Officers are investigating the incident which took place on-board a service travelling from Manchester Airport to Blackpool North.

Just after 7.30pm on Wednesday July 21, a man seated within the train’s carriage was seen to hit a child three to four times on the head.

When challenged by the train conductor, he said: “I can do what I want, he’s my son.”

Officers believe the man in the image may have information which could help their investigation.
