Arthur Cave, the teenage son of Australian rock legend Nick Cave, has died after falling from an 18-metre cliff.
The 15-year-old fell from Ovingdean Gap in Brighton, England, near where the family live. He was found at 6pm on Tuesday.
Police have reportedly said they are treating his death as a tragic accident.
Arthur has a twin brother, Earl, from Nick Cave's marriage to model Susie Bick.
The teenager was found with life-threatening injuries on a coastal path at the base of the cliff by members of the public, who tried to revive him.
However, after being flown to Royal Sussex County Hospital, he died from his injuries.
"He died later that evening of his injuries in hospital," a spokesman told AFP. "The death is not being treated as suspicious."
Nick Cave, 57, and Bick issued a statement: "Our son Arthur died on Tuesday evening. He was our beautiful, happy loving boy. We ask that we be given the privacy our family needs to grieve at this difficult time."
Arthur's parents and twin brother visited the cliff top on Wednesday afternoon and viewed tributes placed there, Brighton's The Argus newspaper reported.
His twin brother left flowers and a note on the beach, The Daily Telegraph in London reported.
The note read: "Arthur - I love you so much. You were a joy to be around and I will never forget you. You were the best brother I could ever ask for. Earl."
School friend Lucy Hopson paid tribute to Arthur at the site of the accident, The Argus reported.
"This news is shocking; being at school with Arthur in the recent two years, I formed a good friendship with him," she told The Argus.
"It saddens me greatly to find out this news, because he was such a kind, hilarious and fun to be around person. Rest in peace Arthur."
Arthur's close friend Ed Bucknall also paid tribute.
"He was one of the nicest guys you could meet, he was so funny and just so much fun," he told The Argus.
"He never said a bad word about anyone.
"I'm devastated, I can't even explain it - I'm just broken.
"I'm not sure what Arthur was doing at the time, I have no idea how he would have fallen."
Just hours before he was found, Arthur had reportedly sent a photo of himself smiling to a schoolfriend through messaging app Snapchat.
Kimya Hajisaeagh, 15, told The Mirror in Britain that she had been friends with Arthur since primary school. She said they had a friend who lived near the cliffs where he fell.
"I just can't believe it. I'm in shock, everybody is in shock," she said.
"I think he was with his brother and a friend at some point that day but I don't know whether he was with him at the time he fell.
"He wouldn't normally hang around here but one of our friends lives near the hillside and he may have been going to visit him, it's just the worst thing ever."
Police said Arthur was with a friend about two hours before he fell.
Fairfax Media understands that it would have been necessary for Arthur to climb over a 1.2 metre fence to get to the top of the cliff from where he fell.
It is understood that Arthur changed schools last year to the exclusive private school, Bede's, near Brighton, where day fees are $29,660 a year.
The Times of London reported that Sussex Police said Arthur's death was not linked to a photograph taken 16 kilometres along the coast of a group of teenagers sitting with their legs dangling over a 90-metre cliff.
A resident who took the photograph said there were numerous fatalities on the cliff edge each year, and that warning posts or fences regularly fell, with rocks, into the sea.
It was reported that Arthur had starred as Borachio in the school's production of Much Ado About Nothing last month.
Last year, Arthur appeared in 20,000 Days on Earth, an award-winning quasi-documentary about a day in the life of his father.
Arthur was shown sitting alongside his father and brother watching Scarface, a violent crime film.
Nick Cave later explained that he had watched "a lot of super violent stuff" with his teenage sons, The Times reported.
