An arson attack on a Melbourne defence manufacturer by a group that allegedly threatened companies supplying Israel is being investigated as an act of terrorism. Investigators allege the group targeted Lovitt because it believed the company was part of the defence supply chain supporting Israel. Those responsible face possible charges of engaging in a terrorist act and preparing or planning a terrorist act. A conviction for engaging in a terrorist act carries a maximum sentence of life imprisonment. The Lovitt attack occurred on the same day as an arson attack on the East Melbourne Hebrew Congregation and violent protests outside an Israeli-owned restaurant in central Melbourne.
