Detectives are investigating an incident of grievous bodily harm in Exmouth which happened in broad daylight at 12.30pm on Tuesday, August 13.
The victim and his partner were driving from Dukes Crescent onto Prince of Wales Drive, Brixington, when they crossed paths with three teenage boys.

Detective Constable Ailsa Mason, of Exmouth CID, said: “The victim was sitting down with his seatbelt on and wearing glasses at the time.
“He suffered serious facial injuries as a result, including deep lacerations and a facial fracture.
“The injury could have been far worse and luckily there appears to have been no lasting injury to his sight.
