Robbie Coltrane’s cause of death has been revealed more than a week after his passing was first reported.

The Harry Potter star, who played Rubeus Hagrid in the popular fantasy franchise, died in a hospital near Falkirk in Scotland on October 14 at the age of 72.

A statement from Coltrane’s agent, Belinda Wright, read: “For me personally I shall remember him as an abidingly loyal client. As well as being a wonderful actor, he was forensically intelligent, brilliantly witty and after 40 years of being proud to be called his agent, I shall miss him.

“He is survived by his sister Annie Rae, his children Spencer and Alice and their mother Rhona Gemmell. They would like to thank the medical staff at Forth Valley Royal Hospital in Larbert for their care and diplomacy. Please respect Robbie’s family’s privacy at this distressing time.”

Wright went on to say that Coltrane was a “unique talent” and that his iconic role as Rubeus Hagrid in the Harry Potter film series “brought joy to children and adults alike all over the world”.

Now, it is being reported by multiple outlets, including The Mirror, that the actor died from multiple organ failure.

According to Coltrane’s death certificate, he was suffering from sepsis, lower respiratory tract infection and heart block at the time of his passing.

Coltrane had also been diagnosed with obesity and Type 2 diabetes.

In the wake of his passing, a number of Coltrane’s co-stars shared some touching words in honor of the star.

“Heartbroken to hear that Robbie is gone. I’ll never forget the smell of cigars and beard glue- a wonderful combination,” Rupert Grint, who played Ron Weasley in the Harry Potter movies, wrote on Instagram. “No one else on this planet could of played Hagrid, only Robbie.”

Grint continued: “Just as Hagrid was in the books and films Robbie was in life- warm, compassionate and hilarious. A giant-hearted man who was still looking out for us even decades later. Sending love to his family. See you on the other side Bobser.”

Daniel Radcliffe paid tribute to Coltrane in a statement via Deadline, saying: “Robbie was one of the funniest people I’ve met and used to keep us laughing constantly as kids on the set.

“I’ve especially fond memories of him keeping our spirits up on Prisoner of Azkaban, when we were all hiding from the torrential rain for hours in Hagrid’s hut and he was telling stories and cracking jokes to keep morale up. I feel incredibly lucky that I got to meet and work with him and very sad that he’s passed. He was an incredible actor and a lovely man.”

Emma Watson, who famously portrayed bookworm Hermione Granger in the films, penned a touching tribute, which was shared on her Instagram Story.

“Robbie was like the most fun uncle I’ve ever had, but most of all, he was deeply caring and compassionate towards me as a child and an adult,” she said. “His talent was so immense that it made sense he played a giant — he could fill ANY space with his brilliance.”
