The inquest into Ian Tomlinson’s death concluded hearing evidence on Thursday of last week.
Dr Kenneth Shorrock, a forensic pathologist, told the inquest on Tuesday of last week that Tomlinson’s injuries were not consistent with a heart attack.
This made him the fourth expert to disagree with the findings of pathologist Freddy Patel, who was the first to examine Tomlinson’s body and suggested he had died of natural causes.
Newspaper seller Ian Tomlinson died in the City of London financial district during the G20 demonstrations in April 2009.
He was trying to find his way home when he was shoved to the ground by PC Simon Harwood. Tomlinson collapsed and died moments later.
Patel did the initial post-mortem, but has since been removed from the Home Office register of professionals.
He was suspended because of his involvement in another, unrelated case.
Also on Tuesday, Professor Robin Williamson, a consultant surgeon, told the inquest, “One cannot rule out coronary artery disease, perhaps acute coronary syndrome, and he was a smoker. But there is precious little evidence in support.”
He went on, “If you put all of that together, you have very strong presumptive evidence he bled from the liver.”
Central to the evidence has been the ECG readings from Tomlinson’s treatment by the emergency ambulance team.
These are not consistent with the heart condition Freddy Patel suggested.
Professor Kevin Channer, who carried out the ECG studies, told the inquest on Thursday of last week, “In my opinion, it is entirely inconsistent that his collapse was due to a primary cardiac problem.”
The inquest has heard from several specialists that “blunt force trauma” to the liver caused huge internal bleeding and killed Tomlinson.
Judge Thornton will reconvene the inquest on Thursday of this week to summarise the evidence.
The jury will consider the evidence for around five days and then give a verdict.
