China Says It Has Detained a British Spy  

SINGAPORE—China has taken into custody an alleged British spy, the country’s national security agency said Monday, as Beijing steps up warnings over national security and the infiltration of foreign spies in the country. 

In a social-media post, China’s Ministry of State Security alleged that MI6, the U.K. foreign-intelligence service, in 2015 recruited a foreign national surnamed Huang and provided both training and “specialized spy equipment for intelligence liaisons.”
