The family of Ian Tomlinson, who collapsed after being hit by an officer at the G20 protests in London, have accused the police of engaging in a cover-up to stop them finding out the truth.
In an interview with the Guardian, Tomlinson's widow, Julia, and son, Paul King, spoke for the first time about the anger, hurt and frustration they have felt in the months since his death.
They said they felt they had been pressured by the City of London police, Scotland Yard and the Independent Police Complaints Commission (IPCC) not to speak out, but could no longer keep quiet because of their concerns.
The family said police had prevented them from viewing Tomlinson's body for six days after his death.
Police initially tried to persuade them there was nothing suspicious about the death and gave them only an edited version of his first post-mortem exmaination.
