The 48-hour police blitz saw arrests made in Kincumber, Bankstown, Manly and Arndell Park and charges laid for weapons related offences, drug detections, outstanding warrants and bail condition breaches.
More than 4000 random breath tests were also conducted across “known hotspots and districts throughout the state”.
Police drug detection dogs were deployed to train stations around the city.
Detective acting Superintendent Glen Parks said Operation Foil had been a huge success.
“Operations such as this one is about keeping the public safe,” he said.
“The fact we were able to get five firearms and 61 knives off the street demonstrates the success of the operation.”
The number of knives carried by young people stood out as cause for alarm.
“It is still concerning that we still have a portion of the community who chose to carry knives; and it’s particularly concerning that a large number of these are young people,” he said.
