Cilla Black’s post-mortem examination was "inconclusive".
An autopsy on the late ‘Blind Date’ host – who passed away at her holiday home in Spain aged 72 at the weekend – failed to determine her cause of death but police are still treating it as "non-suspicious".
Further tests on organ and tissue samples taken from the star have been ordered and will be carried out at a specialist lab in the southern Spanish city of Seville.
A source told the Daily Mirror newspaper: "The autopsy into Cilla Black’s death has been conducted today.
"Further tests will now take place and the police and judicial investigation will continue as is standard practice in a case of this kind."
Cilla – who shot to fame in the 60s with hits including ‘Anyone Who Had A Heart’ and ‘Step Inside Love’ before becoming a much-loved TV host – is believed to have died after suffering a fall after waking from a nap and becoming dizzy from the change in temperature on her sun terrace.
A source shared: "The marks she’s got are consistent with a fall where she’s put up an arm as a defence mechanism. What needs to be determined now is why she fell and whether it was indeed to do with the sudden change in temperature and the effect that had on her – which seems the most likely scenario at the moment – or whether something else triggered the collapse.
"Midday temperatures on Saturday in the area were in the high eighties and we know Cilla wasn’t in the best of health. More tests may be necessary after the autopsy to get to the bottom of what’s really happened.
"There’s no evidence to link Cilla’s death to any criminal act but police and courts generally like to keep an open mind on things. The possibility she fell because she was confronted on the terrace by a would-be burglar has also been looked at and not yet excluded although it is not being seen as a probable scenario."
