Officers are appealing for witnesses following a spate of incidents in which rocks were thrown at vehicles on the A14 at Cambridge. 

Rocks were thrown from the side of the road, causing damage to four passing vehicles, at about 10pm on December 29, between junctions 32 and 33. 

One driver got broken glass in his eye after his lorry windscreen was smashed and two lorry drivers reported rocks had also smashed their windscreens. Another victim said his car bonnet was dented by a rock. 

PC Finlay Betts said: “This reckless behaviour caused serious damage to vehicles but, even more worryingly, put multiple lives in danger and could have resulted in a devastating collision. 

“I am urging anyone who may have any information or has dashcam footage to come forward.” 

Anyone who saw anything or has dashcam footage around the time stated is urged to call 101 quoting 35/95802/23 or visit Cambridgeshire Constabulary's website. Alternatively, contact Crimestoppers, anonymously, on 0800 555111 or via their website.
