US radio DJ, actor and presenter Casey Kasem has died aged 82.
Kasem was best known in the United States as the host of weekly radio chart countdown American Top 40 but British viewers will better recognise his distinctive voice as that of Shaggy from the Scooby-Doo cartoons.
Kasem had suffered from Lewy body disease, a form of dementia, and died days after a judge granted his daughter Kerri the right to withhold food, water and medication from him, against the wishes of his wife Jean.
"Early this Father's Day morning, our dad Casey Kasem passed away surrounded by family and friends," posted Kerri Kasem on Twitter this morning.
"Even though we know he is in a better place and no longer suffering, we are heartbroken.
"Thank you for all your love, support and prayers. The world will miss Casey Kasem, an incredible talent and humanitarian; we will miss our Dad."
Casey Kasem presented American Top 40 in two spells from its inception in 1970 until 2004. He voiced Scooby-Doo's best friend Norville "Shaggy" Rogers in their animated crime-solving adventures between 1969 and 1997 and from 2002 until 2009.
He was also a committed vegan and animal rights advocate, something he once called "very important and much more important than the radio show or the television show that I do or anything else that I do".
