Six hundred Metropolitan Police officers lined the route of the three victims' funeral procession in Shepherd's Bush and a memorial service in Westminster Abbey was attended by Prime Minister Harold Wilson, Leader of the Opposition Edward Heath and many other dignitaries, as well as thousands of police officers from all over the country. More than one thousand members of the public stood in mourning outside the Abbey. Holiday camp owner Billy Butlin donated £250,000 to a new Police Dependants' Trust, and it had soon raised more than £1 million.
