Three people have been detained for allegedly disrupting public order and traffic after a civil disturbance triggered by a chef's death in central China's Hubei Province, authorities said Thursday.

The three, the chef's relatives, were the brother and two cousins of 24-year-old Tu Yuangao, whose death sparked a civil unrest in mid-June in Shishou City, said the city government.

Tu's body was found lying at the gate of the Yonglong Hotel in Shishou on the evening of June 17.

Police found no suspicious injuries. An initial investigation found that the chef had killed himself by falling from a high building, which sparked doubt and anger among Tu's family and the public.

The hotel was burnt and several vehicles were smashed in the unrest.

Experts from the Ministry of Public Security and Tongji Medical Institute carried out an autopsy and X-rays and tested for poisons, showing Tu committed suicide.
