London - British police confirmed Saturday they were probing yat another case of possible excessive use of force in crowd control during the recent G20 summit in London.

A Scotland Yard spokesman declined to give details, but local media reports said it appeared to involve claims by a man who had been hit on the head and thrown to the ground by police.

Confirmation of the latest probe followed a report Friday that a second postmortem had revealed that man a who died after being pushed to the ground by police at the London summit died of internal bleeding, not a heart attack as previously said by police.

A rash of home-made videos from the clashes between demonstrators and police at the April 1 protests in the City of London appear to show other examples of police brutality.

A further inquiry has already been ordered after a video showed an officer hit a 35-year-old woman on the legs with his truncheon a subsequent protest at the death of the first man pushed to the ground.

A police officer suspended after the death has meanwhile been interviewed under caution on suspicion of manslaughter, a statement from the Independent Police Complaints Commission (IPCC) said.

The victim - Ian Tomlinson, a 47-year-old newspaper seller - was not part of the protests but walking home with his hands in his pockets when pushed to the ground from behind by police.

An initial postmortem had suggested Tomlinson died of coronary artery disease, but a subsequent postmortem - carried out at the request of the IPCC and Tomlinson's family - found the death was due to "abdominal haemorrhage", cause of which had yet to be ascertained. (dpa)
