According to French police, Jim Morrison's memorial bust was stolen from his grave 37 years ago.
It said in an Instagram article that the door statue was found in Paris in an investigation conducted by its finance and anti-corruption department, which had nothing to do with the original theft.
Morrison's grave has long been a tribute in unusual ways by fans of rock bands - graffiti is doodled around the corner of the poet's famous père-lachaise cemetery, which also houses the graves of Edith Piaf and Oscar Wilde.
There is little information about the investigation, and no suspects were named in the burglary of the singer statue that died in 1971.
Sources close to the investigation told the news agency that in France-France-Presse, police found out while investigating the fraud.
It is not clear whether the bust will be put back on the grave, and the cemetery curator told Lefigaro: "The police did not contact us, so I don't know if the bust will be returned to us."
Croatian artist Mladen Mikulin carved the statue from White Marble to mark the 10th anniversary of the singer's death. But it disappeared in 1988, when the bust was placed on the site seven years later.
A photo released by French police shows the statue's mouth and nose missing, just like before it was stolen.
Speaking at the Rolling Stone, the representative of Morrison Estate said it was "good to hear the news" when he heard the news of "historic", adding that Morrison's family wanted it "good to be" on the grave and therefore was glad to see it had been restored".
This is not the first time that the singer's grave has become the source of controversy. On the 20th anniversary of his death, fans rioted about his grave and had to be dispersed by police.
Morrison died suddenly at the age of 27 when he lived in the Marais region of Paris.
His girlfriend, Pamela Courson, found him dead in the bathroom. A doctor's report said the cause of death was aggravated by heart failure.
Morrison is the son of a U.S. Admiral and was born in Florida in 1943.
He formed the door with keyboardist Ray Manzarek in Los Angeles in 1965
The band’s name is inspired by Aldous Huxley’s “Gate of Perception”, which involves the author’s use of drugs.
