The nephew of actor Liam Neeson has suffered a serious head injury after falling from the top of a seaside phone booth.

Police say 31-year-old Ronan Sexton was out with friends when he fell about 20 feet (6 meters) from a phone kiosk beside the pier in Brighton, southern England, on Sunday.

He was admitted to a local hospital but later transferred to a specialist neurological center.

Sussex Police said Friday there were no suspicious circumstances to the incident.

Sexton's mother, Bernadette, is the sister of Northern Irish actor Neeson.

Neeson's wife, actress Natasha Richardson, died in March 2009 after hitting her head while skiing. Neeson said in February he had found it hard to accept her death, telling "60 Minutes": "It was never real. It still kind of isn't."
