An autistic man Tasered multiple times by police has won a £100,000 payout and an apology from the force.

Michael Gilchrist, 60, who has bi-polar disorder and learning difficulties, has also won an appeal for a probe into whether racism played a part in the incident.

The single dad-of-two was left with post-traumatic stress disorder after he was doused in CS spray and shocked with a Taser for a total of 72 seconds.

Michael’s mum Novlyn, 83, who now looks after him, said: “I can never forgive the police for what they’ve done.

“They saw there was something wrong with Michael, but showed no care. They treated him worse than an animal.”

Michael, who has autism and suffers from mental illnesses, he was left 'catatonic' after being Tasered

Michael, who lived alone in Wythenshawe, Manchester, became ­distressed as he made his way to see his brother Andrew and cut his hands while breaking windows on June 6, 2014.

Two officers called to the scene said he appeared aggressive and they feared he may have attacked someone because of his bloodied hands, the High Court was told.

One constable squirted CS spray twice while his colleague used his Taser twice, with one shock fired while Michael was on the ground despite there being enough officers to physically restrain him.

PC Samuel Schofield then arrived and discharged his Taser twice, delivering eight shocks lasting 72 seconds over a period of 113 seconds before Michael was taken to hospital.

Official advice is not to use a Taser after CS spray has been deployed because it may be flammable. Tasers should also not be used if they have already proved ineffective.

Michael was taken to Wythenshawe Hospital and later diagnosed with PTSD.

Retired social worker Novlyn said: “He wasn’t able to communicate at all. It was horrendous.”

Michael later gave up his gardening job and moved in with Novlyn. He started to receive treatment and medication but withdrew and “was lost in himself”, she said.

High Court judge Mrs Justice O’Farrell found that PC Schofield’s use of the Taser was unjustified.

She ordered Greater Manchester Police to pay £85,000 into a Personal Injuries Trust for Michael plus £15,000 to set it up and costs, amounting to a total £325,000.

Chief Constable Ian Hopkins offered a “sincere and unreserved apology”.

Assistant Chief Constable Nick Bailey said Michael’s experience was “a matter of sincere regret”.

The Independent Office for Police Conduct has ordered GMP to reinvestigate its use of force and also Novlyn’s allegation her son was targeted due to his race – a claim GMP previously dismissed.

Novlyn said: “I believe they saw him as a black man and thought he must be ­aggressive. He never attacked anyone.”
