Rik Mayall's wife Barbara Robbins has said that the comedian "suffered an acute cardiac event" before his death at their home in London on Monday.
According to the BBC, Ms Robbins said it happened after the comic returned from a morning run. She made the comment after the West London Coroner's Office said the post-mortem examination of 56-year-old Mayall had proved inconclusive and further tests were required.
In a statement, Ms Robbins said: "We now know that our darling Rik suffered an 'acute cardiac event' at our home around midday on June 9th. He had just returned from his usual run and many people had seen him that morning."
She also thanked the public for their messages of support and the press "for their discretion at this time and for all the wonderful coverage that you have given Rik - it would have made him very happy.
"We always knew that Rik was well loved but we are all overwhelmed by so many joining us in our grief."
