Officers want to find the youths, who are said to be about 14/15 years old in relation to the damage at Dashwood Square in Newton Stewart on Monday night at 10.20 pm.
It’s alleged they threw stones at a Stagecoach bus sitting at the bus stance. As a result, a window on the door of the bus was smashed. The damage is estimated to be about £3-400.
No-one was injured in the incident.
Constable Rachael Jackson said: “This attack could quite easily have caused an injury and was quite reckless. We want to speak to a group of young people who were seen at the bandstand. It is a male from this group who was seen to throw a stone and smash the window. The group consisted of three males and six females, and anyone who can help in this enquiry is asked to call us on 101.”
