His death has prompted tributes from across the wrestling community.
Writing on Twitter, ICW said: "We are heartbroken to learn of the tragic death of ICW World Heavyweight Champion, Adrian 'Lionheart' McCallum.

WWE wrestler Cedric Alexander said he was "crushed" to hear of McCallum's death, while fellow WWE star Paige - real name Saraya-Jade Bevis - said she would be "forever grateful" to have known him.
Pete Dunne, the longest-reigning WWE UK champion, tweeted: "I always looked up to Lionheart's professional approach to wrestling when it was far from that at the time. People like him were pivotal in the growth of a scene that has lead to so many people being able to do this for a living."
British wrestler Will Ospreay, who currently competes in Japan, said: "Every time I've met you, you have been nothing but a sweetheart. I honestly cannot believe I'm writing this tweet.
"Devastated doesn't cover how I feel."

"Heartbroken for the whole wrestling family tonight," he said. "What a talent and what a lovely guy. He will be sorely missed."
Lionheart was one of the mentors in BBC Scotland series Rogue to Wrestler, where eight recruits competed against each other to become professional wrestlers.
