Dozens of people have been arrested across Sydney's public transport network as part of the city's biggest police crackdown since stay-at-home orders were lifted.
Officers targeting anti-social behaviour, violence and weapons offences aboard ferries, buses and trains arrested 86 people during Operation Colossus on Friday and Saturday.
More than 430 infringement notices were also issued and more than 400 searches conducted, while 310 people were moved on and 18 prohibited weapons seized including knives.
Assault, drug possession, robbery and dealing with criminal proceeds were among the offences dealt with during the high-visibility blitz, police say.
They included a man allegedly stopped with a flick knife in his backpack at Panania who was also charged with attempted stalking in relation to a domestic violence incident.
A man apprehended at Parramatta is alleged to have been carrying more than $21,000 in cash, prescription medications and other goods suspected of being stolen, while another at Guildford is accused of having $5400 cash, ice and GBL among his belongings.
During a later search of a home at West Ryde officers allegedly found an automatic pistol under a mattress, as well as ammunition and firearm parts.
A 30-year-old woman stopped for a breath test at Cambridge Gardens, in the city's outer west, was allegedly holding 20 packages of edible cannabis lollies.
"As more people resume travel on public transport and move freely throughout Greater Sydney, our priority is keeping commuters safe and we want all travellers to know police are here to help," Superintendent Despa Fitzgerald said on Sunday
"During the two-day operation, the majority of commuters were kind and considerate toward one another and police.
"Unfortunately, there were a small minority of individuals who put themselves and others at risk with unlawful behaviour and they have been dealt with accordingly."
