The incident happened on Tuesday [13 August]
Detectives are investigating what they've called a 'shocking' attack in Exmouth on Tuesday lunchtime [13 August].
The victim and his partner were driving from Dukes Crescent onto Prince of Wales Drive when they were crossed paths with three teenage boys.
This group became abusive to the victim before one punched him in the face through the open car window.
DC Ailsa Mason 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.
“This was an unprovoked assault in a residential area in broad daylight. The offenders attacked the victim as he waited to pull out of a junction after walking deliberately slowly in front of his car to instigate the confrontation.
“Following the assault a number of members of the public from the immediate community came to the aid of the injured man.
“This victim could have been anyone and it’s a deeply concerning crime.
“The offenders are described as all being white teenage boys. One was about 6ft tall, 17-years-old to 18-years-old, of a medium build, with blonde straight hair which was longer at the top and short on the sides. He had a fine but prominent nose and was clean shaven. He wore a clean white t-shirt.
“The other male was described as white, around 5ft 9ins, about 17-years-old and of proportionate build. He had dark hair which was cut in a blunt style, straight across the front and longer around the hairline. He had a square face with a smallish nose and wore a faded black jumper with a large motif on the chest.
“This is a shocking incident and we need to identify the people involved.”
