A murder investigation has been launched after a man was reportedly stabbed to death aboard a South Western train travelling towards Waterloo through Surrey.

A spokesman for British Transport Police confirmed this afternoon (January 4) an incident had been reported at 1.15pm on the 12.58pm South Western Railway service between Guildford and Waterloo.

They confirmed the victim of the attack suffered a fatal stab wound and died in the scene, amid reports of a “vicious fight” aboard the train.

It is believed as of 4pm, officers are still hunting for the murder suspect in the area surrounding Horsley railway station as well as the Clandon area.

Detective Superintendent Gary Richardson from British Transport Police, said: “This was a shocking and violent attack which took place on-board a train in broad daylight. Officers from BTP are with the family and have deployed a specially trained family liaison officer to support them through this difficult time.

“We know that this was an incredibly frightening incident for passengers travelling on the train. We believe that the suspect and victim boarded the train at London Road at 1.01pm and we would encourage who was on this train to come forward regardless of whether or not they think they can help our investigation. We believe the suspect departed the train at Clandon station.

“Passengers and members of the public can expect to see an increased presence by BTP and Surrey Police officers at Horsley and Clandon as our enquiries continue.

“We would advise anyone in the local area who sees anyone they think maybe the suspect to contact 999 immediately.”

Anyone who witnessed the incident or with any information should contact BTP by sending a text to 61016 or by calling 0800 40 50 40 – quoting reference 210 of 04/01/19. Or you can ring Crimestoppers anonymously on 0800 555 111.
