Inspector Heatley said: "We received a report shortly before 10.45pm on Tuesday, 6th September, that a rock had been thrown at a vehicle travelling in the area. The rock smashed the front passenger window of the vehicle - injuring an 18-year-old woman on the face.
"She required hospital treatment for her injuries. We are investigating reports that the rock may have been thrown from a nearby alleyway. In light of recent incidents of anti-social behaviour, I am also appealing to those involved to keep a cool head and think about the consequences of your actions which could lead to a criminal record.
"Officers will also continue to provide a visible policing presence in the Downpatrick area and police would appeal to anyone who witnesses any anti-social behaviour to contact them. If you have any information, mobile, or dash-cam footage that could help us with our ongoing investigation you can contact police on 101 quoting reference number 2019 of 06/09/22.
"Alternatively, you can submit a report online using the non-emergency reporting form via the following link www.psni.police.uk/makeareport/."
