The man who died at the G-20 summit in London after being hit and shoved by an unprovoked policeman died of internal bleeding, not a heart attack, a second post-mortem autopsy has revealed. The masked police officer caught on tape outside the summit pushing and hitting Ian Tomlinson, who was not a protester, is being questioned under suspicion of manslaughter. Two officers have been suspended for police brutality after inquiries into policing during the summit. The first pathologist to examine Tomlinson said he died from a heart attack. Police originally mentioned nothing of their violent interaction until video and photographic evidence poured in. The hedge fund manager who filmed the video said he's happy he came forward or the death "would have been swept under the rug."
