Youths allegedly committed three different lots of property damage in Katherine, including damaging a service station, smashing a house window, and damaging two cars, with police investigating if they were committed by the same group.

Police director of communications Mark Wilton said in a statement that there were three incidences in Katherine involving youths on Sunday night-Monday morning that police are investigating possible links between.

Mr Wilton said that on Sunday night about 10.30pm police received a report that up to 10 youths were near a service station on Katherine Terrace, with one allegedly armed with a knife.

He said one of the youths was alleged to have smashed a car window before the group ran off.

While at about 12:15am, police received reports that a group of youths allegedly entered another service station on Bicentennial Road, stealing small items, causing damage, and running off.

Mr Wilton said that about 1:15am, youths allegedly broke a window at a house on Grevillea Road, and damaged a vehicle before running off.

The offenders have not been caught and police are still investigating to see if they same youths were involved in all three incidents.

Police are asking anyone with information, particularly CCTV or dashcam footage, to call them on 131 444, or to make an anonymous report to Crime Stoppers by calling 1800 333 000 or through the website.
