“It’s very commendable … they were lucky to get out without getting injured as well,” he said.

“You gotta take your hat off to them, the house went up so quickly, to do what they did and get out without injuries.”

He said police would assist witnesses.

Neighbour Kazem Abdulahi said the fire was “huge”.

He said his brother, a friend, and a neighbour attempted to help the man escape the fire but were unsuccessful.

“They smashed the door, broke the door, tried to go in, but the fire was very [bad] … the fire came out, the ceiling [fell down] because of fire, they couldn’t go inside.

Mr Abdulahi said firefighters attempting to gain access to the building were also driven back.

“When they broke in and smashed the door to try to go in, the fire [fully came out] and they couldn’t go inside, the fire was terrible,” he said. 

“I’m sorry. Very nice guy.”
