Inspector Peter Robertson from Wagga police said a drunk and drug-effected 17-year-old was found in the CBD in the early hours of Sunday morning. 

The teenager was taken home to his grandparent’s house and allegedly started “trashing his bedroom” when he went inside. Officers attempted to assist the grandparents and during a scuffle one of them was assaulted.

The teenager will be dealt with under the young offenders act.
