SA Police have noticed an increase in antisocial behaviour in the vicinity of the Belair mountain biking trails, surrounding streets, and on trains and train platforms.
There have been incidents of objects being thrown at cars on Belair Road and Old Belair Road.
Throwing objects on roads and at cars can cause serious injury and even death.
Police have also received reports about dangerous bike riding on the roads leading to the trails around the Mitcham and Lower Mitcham areas.
With Easter and the School Holidays approaching, SA Police support young people being involved in healthy, physical activities including mountain bike riding; however, we need to consider the safety of the whole community.
Police encourage parents and caregivers to discuss safe and responsible riding.
