A woman who died in her London bedroom has been discovered dead after her cleaning machine went missing, police said.
A post-mortem examination revealed the woman died of asphyxia by hanging and that she died of carbon monoxide poisoning, said Metropolitan Police.
It comes after a woman was found dead on a house terrace in south London last week.
She was discovered unresponsive in her bed with the door closed.
She had been found with carbon mono poisoning.
