More raids linked to Vic NYE terror plot

Police have raided four Melbourne houses as part of ongoing investigations into a man's alleged Melbourne New Year's Eve terror plot.

Ali Khalif Shire Ali, 20, was arrested on a Werribee shopping strip on Monday and charged a day later for plotting to carry out an attack at Federation Square.

Police on Wednesday raided homes at Tarneit, Coolaroo, Glenroy and Berwick and say their main inquiries are complete and no further arrests are expected.
