Specialised Organised Crime detectives and Arson Squad officers attended the premises on Friday morning to continue the investigation. The home was extensively damaged.
Resident Lorraine Rodgers said she wasn’t allowed back into her home until after midnight. ‘I was inside watching television when I heard what I thought was a car crash,’ she said. ‘I went outside and everyone was yelling and screaming. We thought we were going to lose our house.
‘It was just ridiculous. The whole unit was on fire.’
It was the second such case attended to by police that day, after they responded to reports of possible toxic chemicals inside a unit on Cleaver Street, West Perth.
