Family Pay Tribute To Ryan Harrison
The family of a 22-year-old man who died after he was hit by a train following an altercation at a railway station have spoken of the loss of their "ray of sunshine''.
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.
Three men were arrested on suspicion of murder and later released on bail.
In a statement issued through British Transport Police, Mr Harrison's family said: "Ryan was the biggest, brightest ray of sunshine for us. He loved life, his family and his friends.''
Detective Chief Inspector Iain Miller, senior investigating officer, said: "Our thoughts remain with Ryan's family as they try to come to terms with what happened. This is clearly a very painful and difficult time for them.
"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 Ryan?s death, which we are currently treating as suspicious.
"Three men were arrested in connection with the incident before being questioned by detectives. They have been released on bail pending further enquiries until May."
