A CCTV image has been released of a man police are looking for after a driver threatened a man with what appeared to be an extendable baton in Theale.
There was an altercation between two motorists in the Co-op car park in High Street at around 2.40pm last Wednesday.
The driver of a white vehicle, thought to be an Audi Q7, threatened the driver of a small dark car before driving off.
Police believe the driver making the threat had an extendable baton. No-one was injured in the incident.
Investigating officer PC Nicholas Milnes said: “We are releasing a CCTV image of a man as we believe he might have vital information about the incident.
“If you are the man in the CCTV or you think you recognise the man please contact police immediately by calling 101 and quoting reference 903 22/3.”
