A Chinese man who sold 500 pictures of the country's first aircraft carrier has been detained in a spying investigation, local media reported, the latest web user allegedly exploited by foreign intelligence agencies.
The man, surnamed Zhang, began taking pictures of the Liaoning -- a Soviet-era vessel bought from Ukraine -- after he was contacted online by an individual claiming to be a "magazine editor", Dalian Television reported.
Zhang was one of two men detained last year by police in Dalian, the northeastern port where the Liaoning was refitted before going into service in 2012 and has since undergone regular maintenance.
Zhang took pictures of the vessel from April until August when authorities discovered he had 500 pictures of the Liaoning, which had been supplied to his contact.
The other man, surnamed Han, received 90,000 yuan ($14,400) for taking pictures of Chinese military equipment from a "reporter" who contacted him online after he posted his CV seeking employment, according to the report.
Communist China takes an extremely strict approach to its national security and state media have previously reported on web users in the country being "lured" by foreign spies when looking for jobs and friends online.
In May, a Chinese snack bar owner from the southern province of Guangdong was jailed for 10 years for disclosing military secrets, including documents and photographs of material, to "foreign intelligence agencies", state media said.
President Xi Jinping has made security concerns a top issue, and last November state media reported that China adopted a new counter-espionage law aimed at a "more comprehensive state security".
China in 2013 set up a national security commission, which observers said would have parallels with the US National Security Council.
