A 67-year-old woman was travelling along the southbound carriageway of the A428 with her 16-year-old granddaughter in her Volkwagen Polo towards the Barford Road roundabout at 8.30pm on Tuesday (September 3) when a bottle struck her windscreen, causing half of it to shatter.Fifteen minutes later a 22-year-old woman was driving her Ford Fiesta along the same stretch of road when she heard a smashing sound. When she stopped, she noticed damaged to her windscreen, also caused by a bottle.Pc Craig Wheeler said: Throwing objects at vehicles is very dangerous and puts lives at risk. The drivers were left extremely shaken and not seriously hurt but it could have been a lot worse. I would appeal to anyone who knows who is responsible to contact police. INFORMATION: Anyone with any information should call police on 101 or Crimestoppers, anonymously, on 0800 555111.
