 The nephew of film star Liam Neeson is today in hospital with a 'serious head injury' after falling 20ft from a telephone box on Brighton promenade. His mother Bernadette Sexton, the sister of Irish film star Mr Neeson, was at her son’s bedside on Thursday, her partner Harry Shannon said. Speaking at the family home in Worthing, West Sussex, Mr Shannon said: “Bernadette is not in at the moment because she has been at the hospital all day in Haywards Heath visiting Ronan. “I do not want to comment further.” 
 
 He said Taken and Schindler’s List actor Mr Neeson, 62, had been in contact with his sister since the devastating accident last Sunday. She's been a tower of strength to us in hard times in the past.” 
 
 A Sussex police spokesman said: “Just after 4am on Sunday June 22 a 31-year-old Worthing man had climbed on to the top of a telephone kiosk outside Brighton Pier when he fell 20ft to the ground, sustaining a serious head injury. 'He was taken to the Royal Sussex County Hospital and was later transferred to Hurstwood Park Hospital in Haywards Heath where he is currently in a critical condition. '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.' Mr Neeson faced his own heartbreak five years ago when he lost his wife, actress Natasha Richardson, who died aged just 45 in a freak skiing accident in Quebec, Canada. She said: “She was just a wonderful friend, sister-in-law and auntie to my kids. Bernadette has five children, Emily, Conor, Louis, Manus, and Ronan, is the youngest. The actor, who lives in New York with his two teenage sons, said: “Her death was never real. 'It still kind of isn't. There's periods now in our New York residence when I hear the door opening, especially the first couple of years... anytime I hear that door opening, I still think I'm going to hear her.” 
 
 His sister Ms Sexton also paid tribute to her sister-in-law at the time of her death.
– Five years after his wife suffered a fatal head injury in a skiing accident, Liam Neeson is dealing with a similar family trauma, reports the Daily Mail. The actor's 31-year-old nephew, Ronan Sexton, fell 20 feet from a telephone box onto the pavement in East Sussex, Britain, and is in critical condition with head injuries. Sexton, the son of Neeson's sister, Bernadette, had been out with friends when the stunt went wrong about 4am Sunday, reports the Telegraph. Earlier this year, Neeson said the death of Natasha Richardson still didn't seem real.
