Search under way for missing hiker on Hong Kong’s Lamma Island
Zheng To, 52, went hiking after arriving in Hong Kong from mainland China for a short business trip

Hong Kong authorities are searching for a man from mainland China who went missing during a hiking trip to Lamma Island on Saturday, with one of his last known messages to a colleague saying he suspected he had lost his way.
Zheng To, 52, arrived in Hong Kong the same day for a short business trip and was staying at a hotel in Kwun Tong.
On Saturday morning, he told colleagues that he planned to hike on Lamma Island.
In the afternoon, he sent a message to a colleague via WeChat and said he suspected he had lost his way and that his phone battery was running low at 4.50pm.
He said he was still finding his way out in another message and reassured the colleague he was safe while turning down a suggestion at 6.55pm to get help.
But Zheng failed to return to his hotel and could no longer be reached, prompting his colleagues to file a missing-person report with police on Monday.
Emergency services, including the Fire Services Department, Civil Aid Service and police, have mobilised a search operation.
