Forensics have been spotted at a railway station.
Part of the platform at Borough Green and Wrotham was taped off while a specialist officer investigated.
He was joined by two police constables who were also at the scene.
One resident who lives nearby said they were stopped from going over the bridge as the incident was just below.
They added: “It was obviously quite an incident as the trains were stopped.”
A second person commented: “We heard it was a serious altercation between two men.”
Kent Police said the incident was dealt with by the British Transport Police.
They have been approached for more information.
