Liam Neeson's nephew is said to be in a critical condition after falling from a 20-foot telephone box on a night out in Britain.
Ronan Sexton (30), the son of the actor's sister Bernadette Sexton, suffered serious head injuries after the fall at 4am in Brighton on Sunday.
Ms. Sexton is said to be at her son's bedside where he is fighting for his life, according to the Worthing Herald newspaper.
Police are not treating the incident as suspicious.
A Sussex police spokesman said "Just after 4am on Sunday, June 22nd, a 30-year-old Worthing man had climbed on to the top of a telephone kiosk outside Brighton Pier when he fell 20 feet to the ground, sustaining a serious head injury".
"The man had been enjoying a night out with friends, who were present when he fell, and the incident is not being treated as suspicious. There is no further police investigation" he added.
He was taken to the Royal Sussex County Hospital and later transferred to Hurstwood Park Hospital where he is currently in critical condition.
Five years ago, Neeson's wife Natasha Richardson died after hitting her head while skiing in Canada. The 'Taken' star (62) now lives in New York with their two teenage sons.
