The 50-year-old said he was doing maintenance on the property during the afternoon of Monday, February 15 when he heard a thud on the ground.

He said he turned to find a young man behind him and a tussle between the pair ensued, where Mr Cenci managed to grab a hold of the young man's backpack full of spray cans.
