Six men have been arrested after the Derbyshire Police helicopter was used following an assault on a taxi driver.

He pulled over on the A617 to call police but was punched several times in the head before the group fled.
The helicopter directed officers on the ground and six men were detained within a 25-minute period. The suspects are being questioned by police.
The 36-year-old taxi driver, who is from Sheffield, was taken to hospital in Chesterfield for treatment to head injuries.
