CONCERNS are growing after an official who works for an international arm of the Scottish Government was reportedly detained in China.

Simon Cheng Man-kit is missing after crossing the border for a business trip, according to local media.

According to reports, he was on his way back on a high-speed train when he called his girlfriend and told her he was approaching the border when he lost contact, according to HK01. "Pray for me," he added.

The Hong Kong Free Press (HKFP) said the trade and investment officer at Scottish Development International had attended a business event in Shenzhen, in south-eastern China, on August 8, but failed to return.

A Foreign and Commonwealth Office spokesman said: "We are concerned by reports that a member of our team has been detained while returning to Hong Kong from Shenzhen.

"We are providing support to their family and seeking further information from authorities in Guangdong province and Hong Kong."

The Scottish Government said it was concerned for Mr Cheng's welfare and was liaising with the Foreign Office.

A spokesman added: "We are aware of this incident and we are concerned for Mr Cheng's welfare.

"We are liaising with the FCO, who are in contact with Mr Cheng's family, the authorities in Guangzhou and Hong Kong, and are seeking further information."

It is understood that although Mr Cheng works for Scottish Development International he is employed by the British Consulate-General in Hong Kong.

Mr Cheng is a Hong Kong permanent resident who had studied in Taiwan and the UK and it is not clear whether he held a diplomatic passport or what documents he used to enter China, the HKFP reported.
