British officials are calling for a criminal investigation into a police attack on a man who died during the G20 protests in London last week, the Daily Telegraph reports. Video of the incident, shot by a New Yorker in town on business, shows a "sickening and unprovoked attack" by police on Ian Tomlinson, said a spokesman for the Liberal Democrat party. Tomlinson, 47, died of a heart attack a short time later. One senior police officer has called the footage “shocking.”
Tomlinson's son, who has also demanded an investigation, noted that his father was struck with "his hands in his pockets with his head down walking away. We want answers now. It's only minutes after that Ian collapsed and had the heart attack."
