The Global Times newspaper named the four as Lu Jun, who officiated at the 2002 World Cup finals but is now retired, Huang Junjie, who has been on the FIFA's international list since 1998, women's referee Shen Huangying and Guangdong referee Zhou Weixin.
The head of the Chinese Football Association (CFA) Nan Yong and referees committee chief Zhang Jianqiang were arrested last week for their part in the scandal, which has also taken in more than 20 other officials.
Lu, 50, earned the nickname "golden whistle" for his reputed integrity after China's "black whistles" matchfixing scandal of the early years of this century.
"It is not a surprise that referees are involved," he told the Beijing Times at the weekend.
"As far as I know, Huang has been taken away by the police to cooperate in the investigation. Lu has retired. I don't know if he has been cooperating with the investigation."
