Federal Police Deputy Commissioner Michael Phelan lamented that radicalised people could harm others even with rudimentary weapons. 'All you need these days is a knife, a flag and a camera and one can commit a terrorist act,' he told reporters. Deputy Commissioner Phelan acknowledged police did not have the luxury of time in dealing with potential terrorism plots, unlike in drug investigations. They had to act as soon as they thought the public were at risk. Three of the five men who arrested after the raids were released following questioning for most of Saturday. It is expected one of them - a 18-year-old from Narre Warren - will be charged on summons with weapons offences. Two other Narre Warren men, aged 18 and 19, have been released pending further enquiries. Dubbed Operation Rising, more than 200 heavily-armed officers swooped on the Melbourne's south-east about 3am on Saturday, executing search warrants in Narre Warren, Hampton Park, Hallam and Eumemmerring, arresting the men and seizing knives and swords. Authorities have refused to give details of the alleged plot but say police at Anzac activities around Melbourne were the immediate target.
