Chinese authorities say they have detained an individual alleged to be spying for Britain’s foreign intelligence service, MI6.

China’s Ministry of State Security (MSS) said the individual was a foreigner and was trying to collect information inside the country.

It is the latest arrest in a campaign by Chinese security to clamp down on foreign spying.

The British government has not commented on the claims.

The news of the arrest came in a statement issued in a post from the MSS on the WeChat social network.

It said the alleged spy was named “Huang” and came from a “third country,” implying they were neither British nor Chinese. It said consular visits had been arranged following the arrest but did not say from which country.
