A man has been arrested in connection with an assault in Bakewell.
The 41-year-old Doncaster man has been arrested on suspicion of wounding with intent, questioned and released on bail while inquiries continue.
At about 12.50pm on Thursday, August 6, a 51-year-old man was walking along North Church Street with his ten-year-old son following a shopping trip.
A man and woman were walking towards them with two dogs, one of which was not on a lead.
The dog ran towards the victim, who accidentally trod on its paw.
He apologised to the couple but the man allegedly headbutted him hard in the face, causing a significant cut to his upper lip which required stitches.
Anyone with information should call Derbyshire police on 101 or Crimestoppers on 0800 555 111.
