The stress of being struck by a policeman's baton and being shoved to the ground may have triggered a heart attack in Ian Tomlinson, who died at the G20 protests in London in 2009, an inquest heard yesterday.
Pathologist Dr Freddy Patel said it was "well recognised" that a stressful trauma can aggravate a heart condition.
He said he had no evidence that the push had caused a heart attack, but argued there was a "compelling association".
Two other pathologists have contradicted Dr Patel's findings, concluding that Mr Tomlinson did not die of a heart attack but of internal bleeding.
The hearing continues.
