G20 Journalist grabbed by a police Snatch Squad

During the G20 protest in London on the 1st April I was talking to another photographer well away from the area where the police were attacking protesters. We were in the Kettled area a few metres back from a cordon of police in riot gear when without warning a scuffle broke out and, purely by reaction, I shot from over the heads of the people between me and action. The five frame slide show is the result. If anyone knows who the main guy is please let me know that he is OK.
