A 28-year-old Royston man has been arrested in connection with a series of sexual assaults on four women on a train travelling between Knebworth and Hatfield.

A man inappropriately touched four women on board the 14.11 service from Meldreth to London King’s Cross, and when he was confronted by two other men, he became violent and assaulted them both.

PC Sam Sherwood is investigating and is appealing for witnesses to come forward.

He said: “I am really keen to speak to anyone who was travelling on the service and who may have witnessed the incident.

“I would also like to appeal to the two good Samaritans who intervened during the incident as they may also hold crucial information in this investigation.”

It is thought that the four women may have left the service at Knebworth and Welwyn North stations, and police are appealing for them to get in touch.

PC Sam Sherwood added: “Acts like this will never be tolerated on the railway and everyone has the right to travel on the rail network work without fear or intimidation.

“As part of our ‘Report it to Stop it’ campaign we encourage people to report unwanted sexual behaviours in order for us combat sexual offences on the rail network.”
