The Belfast Telegraph reports that forensic experts told a court in Spain's Costa del Sol that the rocker died of natural causes, hours after starting a six-day holiday with his girlfriend.
Moore was found dead in a hotel room during the early hours of Sunday morning.
Paramedics were called around 4am on Sunday to the five-star Kempinski Resort Hotel in Estepona, after Moore's girlfriend raised the alarm.
While forensic experts are satisfied he died from natural causes, they requested further tests on tissue samples taken from his body ahead of a final report.
A Spanish police spokesman said: “Mr Moore died of natural causes and his death is not in any way suspicious. An investigating magistrate has opened a standard inquiry to determine the exact cause of death.”
It is understood a judge has already given permission for Moore's brother, Glen, who arrived in Spain on Monday, to repatriate his body.
Although he had a successful solo career, for many, it was for his time in Thin Lizzy that Moore will be best remembered.
