A van driver who repeatedly struck a police officer with a machete during a routine traffic stop has been found guilty of wounding with intent.
Muhammad Rodwan attacked PC Stuart Outten after he was pulled over in Leyton, east London, on 7 August.
The officer was badly injured and has yet to return to work.
Rodwan, 56, of Luton, had claimed he was acting in self defence. He was convicted of wounding with intent but found not guilty of attempted murder.
In a victim impact statement read out to the Old Bailey PC Outten said: “This incident has changed my life but I hope it has not changed the way I police.”
Rodwan, who has previous convictions for rape and two other machete attacks, was also cleared by the jury of possessing an offensive weapon.
Mrs Justice Carr adjourned sentencing until Friday morning.
PC Outten suffered six blows to the head from a 2ft-long blade after stopping Rodwan’s white van for having no insurance.
The defendant said he was not aware at the time that the insurance on his van had expired 12 days earlier.
Following the attack PC Outten said he counted himself “very lucky” to survive, saying “thankfully” his head was hard enough to withstand the onslaught.
Bleeding heavily from deep gashes to the head, broken fingers and a wound to the arm, the Met Police officer Tasered Rodwan twice before subduing him, the Old Bailey heard.
Rodwan told jurors he did not recall punching PC Outten before he was arrested.
In the struggle, the officer pulled some of Rodwan’s dreadlocks out, which was “extremely painful”, and grabbed his throat, he said.
“I could not breathe at all,” Rodwan told his trial.
“It felt like he cracked my throat, squeezed so hard it felt like it was popping.”
Rodwan said he retrieved his machete from the van but could not remember how many times he hit PC Outten with it before getting out.
He said: “I was just trying to hit him to get him away from me.”
The defendant said he did not know Pc Outten had a Taser and had raised the machete up to “try to scare him away from me”.
Rodwan had claimed he had the machete in his van for his gardening work.
The jury was told the defendant had a conviction for rape in 1982.
And in 1997 at Snaresbrook Crown Court he was convicted of two offences of wounding with intent for an unprovoked machete attack on a tenant and his friend for which he was sentenced to nine years in prison.
