The New South Wales police commissioner, Mal Lanyon, on Tuesday alleged Naveed Akram, 24, and his 50-year-old father, Sajid, had recently travelled to the Philippines, which was confirmed by authorities in Manila.

Naveed Akram previously known to security agencies, prime minister says. His gun-owning father, Sajid, was shot dead by police at the scene
