A father was knocked unconscious in an ‘unprovoked attack’ on him and his son in Brunel Road, Luton.
The 49-year-old and 23-year-old were walking along Brunel Road at about 12.30am on July 20 when a man got out of a silver BMW and punched the father.
When the son went to his father’s aid he was also assaulted by the man, who then got back in the BMW and drove from the scene.
Police Inspector Marie Gresswell, investigating, is keen to trace any witnesses.
She said: “This incident appears to be unprovoked and I would urge anyone who saw the assault to contact the police and help piece together exactly why these people where targeted.”
Anyone with information relating to this incident can contact Inspector Gresswell, in confidence, at Bedfordshire Police on 101, or text information to 07786 200011.
