(CNN) -- Malik Bendjelloul, the Oscar-winning director of "Searching for Sugar Man," died suddenly on Tuesday, police said. He was 36.
No crime is suspected in the filmmaker's death, Stockholm Police Sgt. Janne Gyllstedt told CNN.
Gyllstedt would not specify the cause of death and said he was unable to disclose any additional information.
"Searching for Sugar Man," Bendjelloul's critically acclaimed film about singer Sixto Rodriguez, won an Academy Award for best documentary last year. The documentary tells the story of Rodriguez, a singer from Detroit who never gained fame in America but became -- somehow -- a legend in South Africa.
"This is the best story I ever heard in my life," the director said of his decision to make the movie.
After running out of money to make the film, Bendjelloul finished shooting the documentary using an iPhone app.
