Levon Demirian, an Armenian-Australian restaurateur of the Sydney suburb of Epping, was charged with murdering Hagob Levonian of the Sydney suburb of Willoughby. He was also charged with having conspired with Levonian to commit an illegal act by having used an explosive device which would have intentionally and without lawful excuse caused damage to a building and endangered lives of others. When Demirian's home was searched, police found a notebook containing the names, addresses and movements of Turkish Embassy staff as well as books and diagrams on electronic devices and circuitry.
