The 15-year-old son of Australian singer Nick Cave has died after falling off a cliff in Brighton.

Arthur Cave was found with life-threatening injuries on the underpass of Ovingdean Gap on 14 July.

He was taken to Royal Sussex County Hospital in Brighton but later died from his injuries. Sussex Police said they are not treating his death as suspicious.

The singer and his wife Susie have paid tribute.

They said: "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."

Schoolfriend Lucy Hopson added to The Argus: "This news is shocking, being at school with Arthur in the recent two years I formed a good friendship with him.

"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 and his brother Earl appeared in their father's 2014 docu-drama 20,000 Days On Earth.
