Two teenage girls are among three people who have died in crashes which happened a few hours apart.
Two girls, aged 17 and 18, were killed in a collision involving a bus and a car in Rutland yesterday afternoon.
The collision occurred at about 1.25pm, in Empingham Lane, Tickencote, Rutland and involved a blue Peugeot 206 and a single decker bus.
The girls, who have not yet been named, were the driver and passenger in the car. They were pronounced dead at the scene.
The girls are understood to have been pupils at Oakham School.
