Irish singer Sinead O'Connor was pronounced dead Wednesday at a south London residence by police officers responding to reports of "an unresponsive woman", the capital's Metropolitan Police confirmed Thursday.

"A 56-year-old woman was pronounced dead at the scene... the death is not being treated as suspicious," the force said in a statement which did not name O'Connor, in line with UK policing protocols.

"Police were called at 11:18 hrs on Wednesday, 26 July to reports of an unresponsive woman at a residential address in the SE24 area," the Met noted, referring to a postcode several miles south of central London.

"Next of kin have been notified... A file will be prepared for the Coroner," it added.

In English law, inquests are held to examine violent, unnatural or unexplained deaths. They set out to determine the place, time and type of death, but do not apportion blame.
