POLICE have released images of four men they want to speak to after a mother and son were racially abused on a train.

The incident happened on a Leeds to Skipton train, and the men left the train at Bingley.

It occurred around 8.30pm on Saturday April 21, and British Transport Police have just released security images from the train.

The woman had boarded a Northern service at Leeds, and was travelling with her young son.

A BTP spokesman said: "A group of four men also joined the train and during the journey subjected the woman and her son to racial abuse.

"The four men then left the train at Bingley station.

"Officers would like to speak with the men shown in these images as they may have information which could help the investigation.

"If you recognise them, or have any information which could help, contact British Transport Police on 0800 40 50 40 or text us on 61016 quoting ref: 725 of 21 April."
