Police are now appealing to the public for information and any dashcam footage they may have following the incident, which took place on the M90 between Craigend and Broxden, around 8:10pm on Friday, May 7. A spokesperson for Police Scotland said: “A silver Vauxhall Astra travelling north towards Broxden was struck by a brick that was thrown from the flyover near Craigie Hill, smashing the rear windscreen. “Fortunately the driver was not injured and was able to pull over safely. “A group of youths were seen running off from the flyover, however only one of them has been partially described to us as having blonde hair and wearing a black top. “This has been an unspeakably dangerous and reckless act, as if the front of the car had been struck, the driver could easily have been killed or seriously injured. “At least one other car stopped at the time of the incident, and we would like to speak to the occupants of this car, along with anyone else who may have seen this group on the flyover around the relevant time, particularly if anyone has dashcam footage. “If you have any information that could help us, please call 101 or speak to any police officer. Also, information can be given anonymously through CrimeStoppers on 0800 555 111. Our reference is incident 3538 of 7th May.” A message from the Editor: Thank you for reading this article.
