A teenager from Bourne severed his finger while trying to climb over a fence in the town during the early hours of Sunday morning.
Police, firemen and paramedics were called out to Abbey Road where the freak accident took place just before 2.15am.
The 17-year-old man was freed from being trapped behind the fence by firemen from Bourne who later recovered the severed finger in an area nearby after a joint search with police.
He was taken by ambulance to Peterborough City Hospital for further treatment and a Lincolnshire Police spokesman confirmed that no arrests were made.
The spokesman said: “Police were called at around 2.13am on Sunday to Abbey Road, Bourne, after a report that a local man had severed a finger while trying to climb over a fence.”
