UPDATE, Tuesday, Sept. 23, 9:58 a.m. AEST: A man has been arrested over the fire that killed three people, including a baby, in Rozelle, Sydney.



Adeel Khan, 44, is the owner of the convenience store where the blaze started and who was inside the shop at the time. He has been arrested in hospital while recovering from his injuries.

SYDNEY — A loud bang could be heard thundering through the streets of Sydney's inner west early on the morning of Thursday, Sept. 4.

New dramatic video emerged of the moment a convenience store exploded on Darling Street, Rozelle. Flames took over the building, as glass windows shattered up to 100 meters away. Residents watched on helpless as the scene unfolded. Two residents jumped from the second story to safety and the owner of the store was dragged from under a pile of rubble.

"Flames [were] coming out the window, almost like a Hollywood production ... the building collapsed," Superintendent Johnstone told ABC News.

Bianka O'Brien, 31, and her baby son Jude were asleep in an apartment above the store when the explosion rocked the building. Both died in the tragedy. Her husband survived as he left for work at 3 a.m. in the morning. The body of their 27-year-old neighbour Chris Noble who was sleeping in an adjoining apartment also died in the blaze.

"As horrific as the scene is, we're still holding out hopes that there are survivors," Superintendent Paul Johnstone told ABC News.

"We believe the mother and child was in one room and another occupant was in a separate room," he said. "We are shoring up the walls, if possible, we have cameras so we can get the cameras down into the voids and under this slab that's fallen, all in the hope of finding survivors."

Firefighters worked through the day to search through and clear the rubble.

Police have not revealed the cause of the deadly fire.
