Murder investigation after body found on railway tracks

A murder inquiry is underway after a body was found on railway tracks on the Kent London border.

At first it was believed the death at Knockholt Station on the Sevenoaks to London line was not suspicious, or an accident.

But murder squad detectives were called in after reports that a young man was chased onto the railway line on Sunday evening.

John Ryall reports from Knockholt, near Sevenoaks.
