Friends have paid tribute to a 22-year-old man who died after he was hit by a train following an altercation at a railway station.
The victim, named locally as Ryan Harrison, from Woking, Surrey, was with a friend at Guildford station at 11.40pm on Saturday when he became involved in the confrontation which involved a number of other men.
Shortly after the altercation, Mr Harrison was fatally injured by a train.
South East Coast Ambulance Service paramedics attended but Mr Harrison was pronounced dead at the scene.
His family have been notified and his death is being treated as suspicious, according to British Transport Police.
Friend Jake Lund wrote on Facebook: "cant believe this has happened to such a nice person, rip Ryan".
Sarah Tuffs wrote on Twitter: "R.i.p Ryan harrison, you will be missed by so many, life is too short."
Amir Ahmed also wrote on Twitter: "RIP Ryan Harrison. Still in shock. Gone, but never forgotten."
Two 19-year-old men, from Guildford, were arrested at the scene while a third man, from Cranleigh, handed himself into a police station in Guildford later.
They all remain in custody where they are being questioned on suspicion of murder.
Detective Chief Inspector Iain Miller, senior investigating officer, said: "Our thoughts are very much with the man's family at this acutely difficult time for them.
"They're trying to come to terms with what has happened and at this stage, quite understandably, they have asked to be left alone to grieve.
"The station was cordoned off until the early hours of Sunday morning while forensic officers conducted a thorough search and my team of detectives are working to establish the full circumstances surrounding the death, which we are currently treating as suspicious.
"Three men were arrested in connection with the incident and they remain in custody being questioned by detectives.
"Clearly the man's family will have many questions about the circumstances leading up to his death but at this time the full sequence of events is unclear. However, we will do everything we can to shed light on what took place on Saturday night.
"We'll be making local inquiries, including checking whether the incident was captured by CCTV cameras, but we know that there were a number of other people at the station at the time and want to hear from them.
"If you were there and have any information, no matter how insignificant it might seem, please get in touch."
