A joint police-military team on Thursday rounded up 141 suspected criminals in a dawn swoop at Kasoa-Buduburam.
They are made up of about 50 women.
The suspects are believed to have engaged in cyber-related crimes and robberies.
They include foreign nationals, who are said to have rented several apartments in the area, from where they plan and launch their nefarious activities.
The operation, which was carried out around 12 midnight consisted of over 600 police and military personnel and followed several weeks of intelligence gathering on crime trends and criminal activities in and around Kasoa.
Two police officers – Sergeant Michael Dzamesi and Lance Corporal Mohammed Awal – were recently shot and killed in the area by a gang after they refused to heed to a signal to pull over.
