The 24-year-old man alleged to be one of two gunmen responsible for the Bondi Beach terror attack has been transferred from hospital to prison, police said on Monday.
Police said that the man had been transferred to a correctional facility in eastern Sydney. The complex houses Long Bay Hospital, a high-security wing for medical and psychiatric cases.
On December 14, two gunmen opened fire on crowds at Sydney's iconic Bondi Beach, killing 15 people and injuring dozens. Most of the victims were Jewish people marking the first day of Hanukkah.
Investigators have identified the attackers as a father and son. The 50-year-old father was shot dead by police at the scene, while the 24-year-old son was injured and later charged with 15 counts of murder, 40 counts of causing grievous bodily harm with intent to murder and one count of committing a terrorist act.
Authorities say the attackers had links to the terrorist organization Islamic State. According to officials, several explosive devices and two homemade Islamic State flags were found in the younger man's car.
