The pathologist who came under fire for his report into the death of a man who died at the G20 protests has been found guilty of misconduct in another case.

Dr Freddy Patel’s post-mortem on East Ender Ian Tomlinson, who was struck by a police officer in an unprovoked attack during the 2009 protests, was later contradicted by two other experts.

It has now been ruled by the General Medical Council that the medic acted dishonestly in his handling of another case involving a murder victim’s body.

He failed to properly examine Sally White, who was killed in north London in 2002, deciding that cuts to her liver and bite marks could have been caused naturally.

Last year Doctor Patel was suspended for three months for unacceptable conduct in three other cases.

He was the first pathologist to examine Mr Tomlinson following his death.

Doctor Patel found that the newspaper vendor died from natural causes after a heart attack.

But two independent examiners later said internal bleeding from a blunt force trauma was the cause, along with cirrhosis of the liver.

In Ms White’s case, the GMC panel upheld 29 allegations of misconduct against Doctor Patel.

Their report said he showed “deficient professional performance”.

The pathologist had said there were no signs that Ms White was assaulted, despite bloodstains on her clothes, bed and the wall of the room in which she was found.

It is thought the GMC will decide later this week on the action to be taken against the medic.

Meanwhile, the police officer caught on camera assaulting Mr Tomlinson is to face a misconduct hearing.

In November the Metropolitan Police announced that PC Simon Harwood will answer to allegations that he “pushed and struck” the East Ender.
