WILTSHIRE Police are appealing for witnesses to an incident which occurred on and around the Bridgemead Roundabout on Great Western Way at around 1.05pm on Saturday March 8.
The incident involved a dark blue Ford Focus estate, a white Mercedes sprinter van, and three white men.
It is reported that the vehicles were being driven in a dangerous manner around the roundabout. This was then followed by one man getting out of the blue car and two men getting out of the white van.
An argument ensued and the Focus was damaged.
Police are particularly keen to talk to a man who stopped and got out of a grey Vauxhall Zafira, who tried to defuse the situation and challenged one of the men involved.
Anyone with any information about this incident should contact Wiltshire Police on 101, where information can also be left anonymously.
