Police in New Hampshire say four on-duty Secret Service agents have been involved in a head-on collision that killed the driver of the other car.



The accident happened at about 7pm Tuesday in Wakefield, near the Maine state line.

Police said the agents were passengers in a Ford Taurus heading south on Route 16. A northbound Mercury Sable with three people crossed over the center line and collided head-on into the Taurus.

The Sable driver, 45-year-old Bruce Danforth, died at the scene. The agents and passengers in the other car were taken to hospitals with injuries. Their conditions were not immediately known.

Police are investigating.

It was not immediately known in what capacity the agents were working, but Democratic presidential candidate Hillary Clinton was campaigning in a town hall meeting Tuesday night in Berlin, north of Wakefield.
