A man has been arrested after a suspected road rage attack which left a father fighting for his life.
Police said a 29-year-old man had handed himself into a police station in Solihull after an appeal.
The 37-year-old victim was taken to hospital in an induced coma after suffering serious head injuries when he was allegedly punched in the "unprovoked attack".
It followed a minor collision between a car and a van in the Kitts Green area of Birmingham at around 6.30pm on Friday.
Detective Constable Katie Lees, from Birmingham's violent crime team, said: "This was a vicious attack on a family man who was on his way home to his partner and four-year-old child.
"The victim phoned home as he left work - like he does every night - to say that he was on his way.
"His partner became worried when he did not arrive home and it must have been devastating for them to discover the news that he had been injured in such a random and vicious attack."
