Chinese authorities have arrested four newspaper reporters for extortion and called on the press to ensure such incidents do not happen again, the official Xinhua news agency said.
The journalists worked for the Economic Daily, China Food Quality Newspaper and two other publications, Xinhua said in a report issued late on Monday, citing a notice from the State Administration of Press and Publications.
The reporters extorted money from companies or institutions after learning about problems, demanding cash to ensure negative stories did not see the light of day, Xinhua said.
The reporters all worked in provincial branches of their publications, some of which had not received government permission to be set up, the report added.
