 PARIS (AP) — There's no evidence of foul play or violence in celebrity chef Anthony Bourdain's death in a French hotel room, a French prosecutor said Saturday. 
 
 The famed cook, writer and host of the CNN series "Parts Unknown" killed himself Friday in a luxury hotel in the ancient village of Kaysersberg, Christian de Rocquigny, the prosecutor of Colmar in France's eastern Alsace region, told The Associated Press in a phone interview. 
 
 Rocquigny said there did not appear to be much planning in the television personality's suicide. 
 
 "There is no element that makes us suspect that someone came into the room at any moment," he said, adding that a medical expert had concluded that there were no signs of violence on Bourdain's body. 
 
 Rocquigny said toxicology tests were being carried on Bourdain's body, including urine tests, to see if the 61-year-old American took any medications or other drugs, in an effort to help his family understand if anything led him to kill himself. 
 
 Olivier Nasti, the chef and owner of Le Chambard, the luxury hotel in Kaysersberg where Bourdain took his life, paid tribute to his colleague Saturday. 
 
 "It is with great respect for the leader, the author, the TV entertainer, the visionary Anthony Bourdain that I express all my condolences to his family and to the anonymous people around the world who he made dream so much," Nasti said in a statement Saturday. 
 
 "It is the whole family of French gastronomy that joins me, to renew our deep friendship to our bereaved American brothers," he added. ||||| As the world pays tribute to Anthony Bourdain days after his death, the culinary star was cremated in France on Wednesday, a source tells PEOPLE.

 The Times reports that there was only a “trace of a nonnarcotic medicine in a therapeutic dose” in his system. 
 
 The late culinary star had been open about his history with substance abuse in the past. In the 1980s Bourdain bounced from job to job at restaurants in New York City while struggling with a serious drug addiction, at one point skimming his carpet for paint chips and smoking them, hoping they were remnants of crack, he recalled to The New Yorker. 
 
 He entered rehab and eventually got clean in the early ’90s, but continued to drink both on and off screen with no issues, he said.

 “I was a heroin addict, for sure, and I was a cocaine addict, for sure, but I never stopped drinking,” he told PEOPLE in February. “I never was a person who needed a drink. I’ve never felt the urge to. When I’m home it would never occur to me to sit at my house and drink beer, or pour myself a cocktail.”
