Prepare for even more protests: The 47-year-old newspaper seller who died of a heart attack outside the G-20 summit in London was struck with a baton and thrown to the ground by a police officer in riot gear shortly before his death, new video footage reveals. The tape shows that Ian Tomlinson did not offer any resistance to officers before being attacked from behind and forced to the ground. Witnesses say he was assaulted by police even before the footage begins and was trying to walk away when he was attacked again. The Guardian has also produced sequences of photos from three photographers that confirm the video’s findings. After Tomlinson’s death, London’s Metropolitan police issued a statement complaining that protesters impeded their quest to get him medical help. A police watchdog group is investigating the incident.
