Three people have been arrested in connection with a fatal crash at the weekend.
Thames Valley Police is appealing for dash cam footage or witnesses to the collision on the A33 at 4.06pm on Saturday (April 20) to come forward.
Two vehicles, a black Astra and a blue VW golf, were both travelling southwards on the A33 between Mereoak Park and Ride and the Wellington Country Park roundabout.
The Astra lost control, leaving the carriageway and crashing into trees.
The driver, a 26-year-old man from Basingstoke, was declared dead at the scene.
His next of kin have been informed and are being supported by specially trained officers.
The passenger of the vehicle, a girl in her late teens from Reading, suffered serious injuries and she remains in hospital in a serious but stable condition.
A blue VW Golf, which police said they believe may have been travelling in convoy with the Astra, briefly stopped before driving off from the scene.
Two men, aged 26 and 34 from Basingstoke, and a woman, aged 24 from Woking, have been arrested in connection with the incident. They all remain in custody at the time of writing.
Inspector Justin Thomas, of the joint operations roads policing unit, said: “We are conducting an investigation following this incident in which tragically a man has died and another girl has been injured.
“My thoughts remain with the family of the man who has died at this very difficult time.
“We are asking anyone with information or dash-cam footage of the incident to please come forward.
“Additionally we are asking anyone who saw either of these vehicles or has dash-cam of them to come forward.
“You can provide information through our online reporting page, or by calling 101 quoting reference 43240181466.”
