Police in the Shenzhen city district of Guangming said Monday that two executives of an unspecified local company were detained after they posted the rumor-containing notice at their firm.
A photo posted by the police shows the notice warning company employees that 300 people from the far northwestern region of Xinjiang who were trained by the ISIS had arrived in the city.
Xinjiang is home to members of the Muslim minority Uighur (WEE-gur) community. Uighurs have been involved in several violent attacks denounced as terrorism by Chinese authorities.
