Two men approached a dark green 4×4 car parked in traffic in Drill Hall Road at around 17:30 on Tuesday 26th June.
It’s alleged one of the men opened the driver’s door and assaulted the motorist at the wheel of the 4×4, a 41-year-old man from Ryde. The driver received minor injuries to his face.
There is also an allegation that the second man was carrying a baseball bat and damaged a window of the car.
All three men are believed to have been involved in a loud argument, which would have been noticed by other members of the public at a busy time of the day.
A 28-year-old man from Newport was arrested on suspicion of assault. A 26-year-old man also from Newport was arrested on suspicion of criminal damage.
Both men were bailed until 10th July pending further enquiries.
Further witnesses or anyone with information are asked to contact PC Keith Haywood at Newport police station by phoning 101.
