Beijing - An employee of the British consulate in Hong Kong has received 15 days of administrative detention in the Chinese city of Shenzhen, the Foreign Ministry in Beijing said on Wednesday.
Foreign Ministry spokesman Geng Shuang said the person violated China's public security law but didn't go into details.
"Frankly speaking, this is not a diplomatic issue," Geng added.
The detainment comes as China-Britain ties are growing tense over pro-democracy protests in Hong Kong, a former British colony, over the past few months.
Britain expressed concern on Tuesday over reports that the consulate employee had gone missing in mainland China and may have been detained.
