Rights groups and activists are sounding the alarm about the detention of two Chinese investigative journalists after they reportedly exposed corruption by a senior official in Sichuan province.
Independent journalists Liu Hu and Wu Yingjiao were taken by police on Sunday after they published their investigation, rights groups say.
Critics have long flagged concern about media repression in China, where authorities have arrested and prosecuted journalists, accusing them of causing trouble.
Chengdu police said on Monday that two men, identified by their surnames Liu and Wu and aged 50 and 34, were under investigation for "making false accusations" and "illegal business operations".
The Chinese government has yet to comment on the detentions and criticism from rights groups.
