Police are investigating the deaths of two men in a Perth suburb which lost power during major storms early Monday morning.
The ABC understands the men, both aged 25 and living in the southern Perth suburb of Beaconsfield, had muscular dystrophy, a neuromuscular, genetic disorder which results in the progressive deterioration of muscle strength and function.
Western Australian Police have confirmed their coronial unit is investigating the incident, after being called to the men's residence at 7:30am.
"Both men had pre-existing medical conditions which required medical assistance," the police spokeswoman said.
"The deaths are not being treated as suspicious.
"The investigation will include inquiries into electronic medical equipment they relied on."
Police will prepare a report for the coroner. It is not clear if the two men are related.
A spokesman for Western Power said they were helping police with their enquiries, but declined to comment further.
Muscular Dystrophy Western Australia chief executive John Gummer said he was aware that the two men had died, but he did not know the details of what equipment was being used.
"When storms and power outages occur people relying on electrical equipment should ensure back up batteries and power supplies are fully charged and alarm systems are fully functioning," he said.
