A man has been arrested in connection to the murder investigation at Horsley train station.

At around 6am on Saturday, January 5, police officers attended an address in the Farnham area where the man (no further details) was detained on suspicion of murder.

A 27-year-old woman was also arrested on suspicion of assisting an offender.

DCI Sam Blackburn from British Transport Police, said: "This is a fast moving investigation and I am pleased that overnight we were able to arrest a man following a huge amount of police enquiries.

"The investigation is moving with good progress and we are now confident to say that this is not believed to be a random assault.

"In the moments leading to the violent killing, both men appeared to be involved in an altercation lasting three minutes.

"Nothing justified the extraordinary violence that followed, and we are concentrating our efforts on the on-going investigation."

Police were called to Horsley Station at around 1.15pm

The family of a 51-year-old man, who’s teenage son was nearby when he was stabbed multiple times, are being supported by specially trained family liaison officers.

A post mortem examination is scheduled for early next week.

Police appeal:

DCI Blackburn, added: "We are continuing our appeal for information and I would urge anyone who was on board the train to contact us as soon as possible.

"Even if you did not witness the assault, it is vitally important we speak with you.

"Likewise, if you have any dashcam footage of the Clandon area after 1pm yesterday afternoon, we would like to hear from you."
