Hong Kong authorities launched a search on Thursday for a 51-year-old man who failed to return home after setting out on a hike on Lantau Island the previous day, when the city recorded its highest temperature of the year.
The man, surnamed Chan, left home on Wednesday morning, telling his family he planned to tackle section 8 of the Lantau Trail, which connects Shek Pik Reservoir with Kau Ling Chung on the southern part of the outlying island.
But he did not return overnight, prompting his wife to call police at 8.45am on Thursday.
Rescue teams from various departments were quickly mobilised, gathering at Shek Pik Country Trail to begin the search.

The Fire Services Department deployed its mountain search and rescue team, with an ambulance on standby, while the Government Flying Service was also notified.
