London (CNN) A man described as one of Britain's worst pedophiles has been found dead in jail.

Richard Huckle, 33, who claimed to have abused almost 200 Malaysian children, died at Full Sutton prison in Yorkshire, England on Sunday, the UK's Ministry of Justice confirmed in a statement. UK media reported that Huckle had been stabbed to death.

Huckle received 22 life sentences at the Old Bailey in 2016 for offenses against children aged between six months and 12 years.

The Ministry of Justice confirmed Huckle had died on October 13 but added that it would be "inappropriate to comment further while a police investigation is ongoing."

During his trial, the London court heard Huckle, who worked as a freelance photographer, was arrested in 2014 at Gatwick Airport as he returned home from Malaysia, where he committed most of his crimes. He had confessed to abusing children on a blog he published on the dark web, an area of the Internet not easily accessible to the general user.
