"It was about 1am when the 111 call came in and officers arrived to find two males, aged 19 and 21-years-old and a 17-year-old female on the deck outside a kindergarten. The trio were arrested and later released on pre-charge warning.
"While we don't know what the trio's intent was there is little doubt that the neighbours' actions of ringing 111 allowed us to intervene in a timely manner and prevented any potential criminal activity."
Ms Grace said actions like last night's showed simple interventions, such as local residents ringing 111, could make all the difference in preventing crime.
"You don't have to confront offenders and put yourself at risk, all you need to do is listen to your instincts. If something doesn't feel right it probably isn't and you should ring 111."
