One of Lee Rigby's killers is reportedly fighting for his life in prison after catching coronavirus.

Michael Adebowale is serving a life sentence for murdering Fusilier Rigby on the streets of Woolwich, south-east London in May 2013.

The Sun reported that the 29-year-old Islamic terrorist was removed from Broadmoor last week following a deterioration in his condition.

It is understood he contracted Covid-19 around a fortnight ago, but is not yet in intensive care of on a ventilator.

Adebowale and Michael Adebolajo ran over the 25-year-old soldier close to Woolwich Barracks in May 2013 before stabbing him to death in broad daylight.

The father-of-one died as a result of multiple cut and stab wounds after the attack fuelled by Adebowale and Adebolajo's extremist beliefs, described as a "betrayal of Islam" at their murder trial in 2014.

Adebolajo had claimed he was a "soldier of Allah" and the killing was an act of war.

In a police interview Adebolajo said he and Adebowale lied in wait near the barracks and targeted Fusilier Rigby because he was wearing a Help for Heroes hooded top and carrying a camouflage rucksack.

Adebolajo then gave a witness a handwritten letter containing a speech about fighting "Allah's enemies" and bringing "carnage" to the streets of London.

The murder was widely condemned by the then Prime Minister David Cameron and the Met's Assistant Commissioner Cressida Dick.

Lee's mum, Lyn Rigby, 53, said it "would not be justice" if coronavirus claimed the life of one of his killers.

“We’ve maintained true justice for Lee is to see his killers remain behind bars and serve every day of their sentence,” she told The Sun.
