Two Victorian teenagers and a man in his 30s face dozens of criminal charges after allegedly firing ball bearings and marbles at people, shops and houses in a period spanning almost a year.
The trio, aged 17, 18 and 38, is also accused of starting a series of roadside fires.
Police arrested the trio after a "long investigation" into the alleged attacks at the regional townships of Traralgon, Morwell, Hernes Oak and Moe between June 2018 and March 2019.
They were charged with at least 37 offences each including criminal damage by fire, reckless conduct endangering serious injury, recklessly causing injury and lighting fires during a fire danger period.
The 38-year-old man is due to face Latrobe Valley magistrates court on October 3, while the 18-year-old will front the same court on September 30.
The 17-year-old boy will appear before a children's court at a later date.
