A Japanese star chef was allegedly killed by two diners over a poorly prepared noodle dish, the Herald Sun reported.

According to the senior public prosecutor, Ulrike Stahlmann-Liebelt, Chef Miki Nozawa, 57, sustained fatal injuries following a dispute that escalated with two guests who were unsatisfied with their dish of fried noodles at a restaurant in the northern German island Sylt.

Bild-Zeitung, a tabloid in Germany, reported the suspected men "didn't like the dishes" Nozawa served.

Both suspects, ages 50 and 36, were detained following Nozawa's death and released because of insufficient evidence, police said. The suspects are still being interrogated on a voluntary basis.

Nozawa was taken to a local hospital and treated at the intensive care unit, but passed away on Monday. The autopsy has yet to be released, but his ex-wife told Sylt Rundschau he suffered from severe brain injuries and internal bleeding

News outlets reported the two disgruntled men asked for their money back because of how the dish of fried noodles with beef and vegetables was prepared, then left without paying. The two diners returned later in the night, which is when the altercation erupted and left him nearly dead.

Nozawa was a star chef in Japanese-Italian fusion cuisine and prepared meals for former President of the Soviet Union Mikhail Gorbachev, Denzel Washington and Phil Collins.
