Jimmy Schulz was arrested on September 11 alongside 19-year-old Ratu Viliame James Koroitamana and was on Monday charged with further offences including conspiracy to murder, participating in a criminal group, possessing an encrypted criminal communication device and failing to operate an unmanned aircraft within visual line of sight.
The new charges relate to an alleged separate murder plot that police say Schulz was conducting drone surveillance for on the day of his arrest. Earlier this month, Schulz had been charged with murder over the September 2 shooting of Joshua Macdonald, 40, a mistaken identity killing in which he allegedly flew a drone used in the attack.
Last week, stood-down PE teacher Ashleigh Ann Seeney, 28, was charged as an accessory in relation to the same alleged conspiracy. Schulz is due to face court on Tuesday.
