James Bond Helicopter

Actually there were 2 that landed at the Wall St heliport. We were thinking it was President Obama as he was coming to New York for the G.A. at the UN. It was good timing to be him coming over from JFK and then a huge motorcade went up the FDR. My question is: what the heck kinda helicopter is that?? Its not a chinook and I can't find anything online in my search, only get chinooks, grrr. Any ideas??
