Southampton Police Looking For White Van
Police in Southampton are appealing for witnesses after a white panel van repeatedly rammed an Audi A3 that was at the time driving along Woolston High Street.
It happened about 11.20pm on Sunday, May 13.
The small white van thought to be a Ford then made off south towards Weston after badly damaging the car. The two men in Audi suffered minor injuries as a result of the ramming.
There appears to be no obvious reason why the van decided to ram the car. It had been in front of them but then pulled in and pulled out into the side of it before getting in front and reversing twice into the Audi before making off.
Officers are appealing for anyone who saw the incident or the white van driving erratically in the area to contact them.
If anyone witnessed this incident could they please contact PC Ian Swan from Bitterne Police Station on 101 or call Crimestoppers anonymously on 0800 555 111.

One of the men's targets was Ernest Jones in Portsmouth, taking £57,000 worth of watches.
