AFP - A man died Wednesday after collapsing at a demonstration in London's financial district ahead of the Group of 20 economic crisis summit in the British capital, emergency services said.
The man fell over and became unconcious, prompting a member of the public to call emergency services, a spokeswoman for the London Ambulance Service said.
He was still breathing at the time but soon stopped, and despite attempts to resuscitate him, later died.
Police said the man collapsed inside a police cordon on St Michael's Alley, not far from the Bank of England where thousands of anti-capitalist protesters had earlier converged for a demonstration ahead of Thursday's G20 summit.
Officers checked on the man but were pelted with a number of missiles, believed to be bottles, and decided to move him out off the cordoned-off area, a Metropolitan Police spokesman said.
They carried out CPR (cardiopulmonary resuscitation) until ambulance staff arrived and they took over attempts to resuscitate the man, but he was pronounced dead in hospital.
It was not clear how the man died, but some people had earlier been injured when protesters held in a police cordon for several hours following the march surged against the crash barriers.
"We received a 999 (emergency) call at 7:24 pm (1824 GMT) from a member of the public reporting that a man had fallen over and was unconscious, but was breathing," said the London Ambulance Service.
"At 7:30 pm we were informed by the police that a man at the location had stopped breathing."
Ambulance staff "made extensive efforts to resuscitate him both there and on the way to hospital", she said.
