About 300 police, including members of the Armed Offenders and anti-terror squads, were involved in the raids in which four guns and 230 rounds of ammunition were seized and 17 people arrested, all but one of them charged with firearms offences. According to police, the raids were a culmination of more than a year of surveillance that uncovered and monitored the training camps. Search warrants were executed under the Summary Proceedings Act to search for evidence relating to potential breaches of the Terrorism Suppression Act and the Arms Act.
