The 50-year-old man was discovered by local police in a residential hotel in the Montmartre district, where he had reportedly been staying since his arrival in Paris on May 3.
He was found in a pool of vomit and had a large wound on his chin.
The Italian Embassy stated that the man is currently believed to have died due to “natural causes” and that the cut on his chin is likely the result of a fall.
Identified as Massimo I., the agent was found with a business card from the Presidency of the Council of Ministers – the highest public office under the control of Italy’s prime minister.
French police also found an encrypted security key in a safe, along with a folder containing 85 €20 notes, a USB key, an SD card and an adaptor.
Prosecutors in Paris have opened an investigation into the man’s death.
