The 29-year-old was reportedly moved from the high-security psychiatric hospital in Crowthorne, Berkshire, to a Covid ward after his condition went ‘rapidly downhill’.
It is the second time in recent days that the killer has been admitted to hospital with the virus, according to the Sun.
A source told the paper: ‘He’s in a very bad way and fighting for every breath.
‘It’s reached the stage where it’s a 24/7 battle. If he deteriorates much further, intensive care would be the next step.’
Adebowale, who is said to have tested positive for Covid two weeks ago, is not on a ventilator but is said to be receiving oxygen treatment.
Michael Adebowale and his accomplice Michael Adebolajo ran down the solider, a father-of-one, with a car before launching a brutal machete attack on him near his barracks in Woolwich, South East London in 2013. The former was given 45 years in jail for his part in the bloody attack while Adebolajo got a whole life term.
The Sun also quoted the mother of Lee Rigby, Lyn, 53, who said it would ‘not be just for Covid to take this man (Adebowale) prematurely and end the sentence handed to him’.
“We’ve maintained true justice for Lee is to see his killers remain behind bars and serve every day of their sentence.”
