US President George Bush collided with a local police officer during a bike ride on the grounds of the Gleneagles golf resort while attending a meeting of world leaders.

Bush suffered scrapes on his hands and arms which later required bandaging by the White House physician. The police officer, who it is thought may have suffered an ankle injury, was taken to hospital as a precaution.

The fall did not affect the president's schedule. He went ahead with a dinner hosted by Queen Elizabeth at the G8 summit.
