A man found dead on railway tracks in Kent has now been identified as 23 year old Samir Draganovic from Croydon.
His body was discovered at Knockholt Station near Sevenoaks on Monday morning.
A 37 year old man has been arrested in connection with his death and remains in custody.
Detectives launched a murder investigation after receiving reports that a young man was chased onto the railway line on Sunday evening.
At first it was believed the death at Knockholt Station on the Sevenoaks to London line was not suspicious, or an accident.
Any witnesses are being urged to contact British Transport Police or Crimestoppers.
