The Daily Telegraph reports that Premier Mike Baird and then police minister Stuart Ayres left at 10pm to check into a city hotel while Mr Scipione and Ms Burn left at 11:30pm.
The siege ended at 2:30am on December 16 when police stormed the Martin Place café where hostages Tori Johnson and Katrina Dawson – as well as the gunman Man Haron Monis – died.
