Detention comes amid more than two months of pro-democracy protests in Hong Kong.
An employee at the UK’s consulate in Hong Kong has been detained by mainland Chinese authorities on his way back to the city, his girlfriend has said.
Simon Cheng, 28, was returning from a trip in Shenzhen to his native Hong Kong on 8 August when his girlfriend, Li, stopped receiving communications from him.
A spokesman for the UK’s Foreign and Commonwealth Office said: “We are extremely concerned by reports that a member of our team has been detained returning to Hong Kong from Shenzhen … We are providing support to his family and seeking further information from authorities in Guangdong province and Hong Kong.”
Li said Cheng had messaged her just before he went silent. “Ready to pass through the border … pray for me,” he had written.
More than 10 days later, Li and Cheng’s family have not been able to get in touch with him. Li said Hong Kong immigration authorities told her Cheng had been placed under “administrative detention” in mainland China in an unknown location and for unknown reasons.
The detention of Cheng, who works in the British consulate as a trade and investment officer for Scottish Development International, comes amid more than two months of pro-democracy protests in Hong Kong that have threatened Beijing’s authority over the city.
Cheng’s detention was first reported by the Hong Kong news site HK01. According to Li, he regularly travels to mainland China for meetings and had gone there most recently for work.
Hong Kong immigration officials said in an emailed statement that they have contacted the city’s liaison office in Guangdong province as well as the Hong Kong government “to understand the situation” and provide further assistance to the family.
Hong Kong has been rocked by mass protests triggered by a bill that would allow the extradition of suspects to mainland China. Cheng’s case further underlines fears of a lack of transparency and fairness in the mainland Chinese judicial system and the possibility that Hongkongers may be detained for political reasons.
Under administrative detention, Cheng can be held for up to 15 days without any charges. Human rights advocates say torture and other forms of ill treatment are common under this type of detention.
According to Li, Cheng had not participated in the protests or expressed his position on the movement in any public forums. “As far as I know, he did not attend any of the protests, even the 1 million march. I am just worried about him,” she said.
Li, who met Cheng while he was studying in Taiwan – where she is from – has been calling and writing to British, Chinese, and Hong Kong officials for help.
“He grew up to be a very caring, diligent and hardworking person,” Li said. “Now, he is missing and detained for no reason. This is deeply distressing for his family and friends.”
Li said she and Cheng had discussed marriage, and possibly moving back to Taiwan, but Cheng wanted to remain in Hong Kong. “He said he loves Hong Kong and wanted to sacrifice all he has for his motherland.”
News of Cheng’s detention comes after more than a million Hong Kong residents defied a police ban and poured into the streets on Sunday in a peaceful march, calling for the withdrawal of the extradition bill and other demands.
Hong Kong’s chief executive, Carrie Lam, said on Tuesday she would set up “a platform for dialogue” to tackle complaints against the police, the government’s first attempt at conciliation in weeks.
A rally in Cheng’s name has been called for outside the British consulate on Wednesday.
In recent weeks, Beijing has taken an increasingly hard line against the protests, which it has described as an attempt to start a “colour revolution”. Twitter blocked almost 1,000 accounts associated with the Chinese government on Monday while Facebook also removed seven pages, three groups and five accounts that originated in China.
China has repeatedly warned Britain – the former colonial ruler of Hong Kong – against “interference”. China has appeared irked by Britain’s public rebukes of the Hong Kong authorities’ handling of the demonstrations.
Chinese immigration officials have increased checks at the border between mainland China and Hong Kong, detaining people and checking their phones and other devices.
Police in Hong Kong are also adopting a harder line, and have arrested more than 700 people in relation to the protests.
