Three charged after hurling marbles at business windows

A man and two teenagers have been charged over allegedly using slingshots to hurl marbles through windows of businesses across dozens of suburbs including Docklands.

Police said the incidents are alleged to have occurred between September and December with investigators estimating the damage bill to exceed $1 million.

One damaged window alone cost $150,000 to repair.

Almost 90 incidents have been reported, with the trio allegedly targeting businesses in Docklands, Bentleigh, Collingwood, Cremorne, Mentone, Richmond, South Yarra, and St Kilda.

Port Phillip Crime Investigation Unit executed a search warrant at a home in Cheltenham, about 6am on December 13 in which a 49-year-old man and two boys aged 15 and 16 were arrested.

During the raid, police found and dismantled what they allege was a small cannabis crop. Officers also seized six firearms, four extendable batons and four slingshots, and suspended two firearms licences.

The trio has amassed a total of 274 charges between them, including 258 counts of criminal damage and six counts of possessing prohibited weapons.

Further charges were three counts of reckless conduct endangering serious injury, three counts of cultivating cannabis, three counts of trafficking cannabis.

The 15-year-old boy has also been charged with one count of dealing with proceeds of crime.

The man was released on bail to appear in Melbourne Magistrates' Court on December 19.

The teens were bailed to appear in a children’s court at a later date.

A 52-year-old woman was also arrested at the property and released with intent to summons in relation to the cannabis crop.

All four were known to each other.
