A teenage driver was left with a wound to his throat after a motorcyclist smashed the wing mirror of his car.

The 19-year-old victim, from Bognor, was driving in Chichester with his partner and their baby in their Ford Focus when the incident happened on Friday.

A Sussex Police spokesman said: "A motorcyclist - unprovoked - leant across and smashed the wing mirror to the vehicle. His partner and their baby were also present during the incident.

"The impact caused glass from the wing mirror to travel through the driver's open window and into his throat, and he was taken to St Richard's Hospital in Chichester for treatment.

"The suspect was dressed all in black, and was wearing a black helmet and riding a black motorcycle. He was seen to continue north along Summersdale Road and then left into The Broadway."

Anyone who saw what happened, or who saw the motorcyclist in the area before or after the incident, is asked to contact Sussex Police on 101@sussex.pnn.police.uk or call 101, quoting serial 864 of 05/08.
