A police officer who hit Ian Tomlinson with a baton and pushed him to the ground at the G20 protests has been found not guilty of manslaughter.
PC Simon Harwood, 45, of south London, denied the manslaughter, in April 2009, of Mr Tomlinson, 47, on the grounds that he used reasonable force.
Mr Tomlinson, was pushed as he walked away from a police line in the City of London. He later collapsed and died.
His family said they would be pursuing the case in a civil court.
It is not clear if that will be against PC Harwood as an individual or against the Metropolitan Police.
"After the unlawful killing verdict at the inquest last year, we expected to hear a guilty verdict - not a not guilty verdict and it really hurts," Mr Tomlinson's stepson Paul King, said outside the court.
"It's not the end, we are not giving up for justice for Ian."

Members of Mr Tomlinson's family cried in the public gallery as the verdict was delivered at Southwark Crown Court.
PC Harwood, in the dock, and his wife, in the public gallery, also cried.
The jury of five men and seven women had considered their verdict for four days.
During the trial, the police officer accepted he was "wrong" to have hit and pushed Mr Tomlinson.
He said that, had he realised at the time that Mr Tomlinson was walking away from police lines, he "would not have gone near him".
Father-of-nine Mr Tomlinson, who was a heavy drinker who had slept rough for a number of years, walked 75 yards before he collapsed.
The Independent Police Complaints Commission has said PC Harwood will face internal Met Police disciplinary proceedings later in the year over his actions.
