Belgian kickboxer Frederic Sinistra has died from COVID-19 complications after discharging himself from hospital.
A vocal anti-vaxxer, Sinistra - known as 'The Undertaker' - told his social media followers that he would treat his symptoms away from hospital.
The 41-year-old died in his home in the Belgian city of Ciney. He was reportedly unvaccinated against COVID-19.
As a fighter, Sinistra had won Belgium's national kickboxing title four times, with a record of 39-9.
Sinistra had previously called COVID-19 the "little virus" and "hair flu" in his social media posts, and shared images of himself receiving oxygen treatments, as well as a video of himself struggling to breathe while adding he had "no time to waste with lazy people."
Sinistra's wife announced his death in a Facebook post.
"From the bottom of my heart thank you all for your support and all your wonderful tributes to my husband," she wrote.
"My husband was a generous man with a big heart who wanted to help others no matter what."
Sinistra is survived by his wife, as well as children Celia and Diego.
