A public toilet block at Rawson has been closed after walls and windows were smashed in what police described as an extreme act of vandalism.
Police identified two children - a 13-year-old boy from the area and another under 10-years-old - as responsible for the vandalism at the public toilets as well as a smashing window at the nearby school.
They said two children were captured on CCTV attending Rawson Primary School on Knotts Siding Rd at 2.53pm on Saturday, May 24.
A window of the main classroom was damaged at about 3.15pm. It is believed an object was thrown through it.
Police believe the pair then travelled to the public toilets at Allan Croxford Reserve.
They reported the damage to walls and windows in both toilets as extreme.
A 13-year-old boy was interviewed and received a caution.
Baw Baw Shire has closed the toilets until further notice.
