A British Foreign Office worker has reportedly gone missing in China after telling his girlfriend to "pray for me".
Officials from the UK government department are "extremely concerned" for Simon Cheng Man-kit, who has not been seen for 10 days.
The Hong Kong consulate official failed to return to work after a trip to mainland China on August 8.
Unconfirmed reports claim the 28-year-old has been detained in China while returning to Hong Kong from Shenzhen, where he had been attending a business event.
The trade and investment officer, in the Scottish Development International department, had messaged his girlfriend on the day of his departure as he boarded a train.
He said he was “ready to pass through,” HK01 reports.
Mr Cheng, who lives in Hong Kong, added: “Pray for me.”
His partner - who has not been named - said Mr Cheng planned to arrive back on the same day on the Express Rail Link, but never reappeared.
The police told HK01 that there'd been no arrests, but he'd been listed as a “missing person”.
A spokesperson for the UK’s FCO 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."
