The incident happened on the German island of Sylt, a destination for many vacationers.
It is unclear how the chef was hurt by the two people during a physical confrontation, but Nozawa later died at a hospital from “severe brain injuries and internal bleeding,” according to his ex-wife. The two people subsequently disappeared.
Nozawa has worked out of Sylt since April, according to German news site shz.de. He is best known for fusing Italian and Japanese dishes.
