Last week police in Melbourne's south east ran OMNI operations at public transport hubs in Cardinia, Casey and Greater Dandenong.
The operation ran from Thursday 7 January to Saturday 9 January where police checked more than 160 people and 20 vehicles.
OMNI operations give police additional powers to detect weapon offences within a designated search area, enhancing public safety, eliminating anti-social behaviour, and reducing crime in the process.
Sixteen people were arrested and charged for offences including firearm possession, assault, theft, drug and weapon-related offences.
A 31-year-old woman from Dandenong was arrested on six outstanding warrants for offences including burglary, theft and recklessly cause injury.
Five drug cautions were also issued.
Police also seized items including a handgun, knuckle duster, knives, extendable baton, taser, drugs and cash.
Quotes attributable to Acting Inspector Graeme Stanley
"Local and Transit police worked together as part of the OMNI operation in an effort to identify those carrying illegal weapons and get them off the streets before they could cause any harm in our community."
"Police simply will not tolerate those who break the law or engage in anti-social or violent behaviour that puts the safety of others at risk."
"We will continue to have a highly visible presence in the community and patrol high risk locations to prevent crime and hold offenders to account."
