Youths arrested over Hills slingshot attacks TWO youths and a man have been arrested over a series of slingshot offences, including people being shot at, in the Adelaide Hills. Police have received numerous reports of smashed windows of cars, houses and businesses in Mount Barker, Bridgewater, Aldgate and Stirling since February 14. Marbles and ball bearings were found around the damaged property. Police believe there has been at least one incident where a person was shot at with a sling shot and have received information that another person may have been hit by projectiles from a slingshot. No victims have come forward. Police arrested two 17-year-old youths, of Bridgewater and Ironbank, and a Heathfield man, 18, yesterday afternoon and charged them with carrying an offensive weapon, aggravated assault and eight counts of property damage. It will be alleged that a slingshot with silver ball bearings and marbles was found in a car with the arrested trio.
