Bounty of HK$10m still to be collected
Among the rewards that remain unclaimed is HK$800,000 for the killers of a triad boss and HK$500,000 for a 16.8-carat emerald ring

Rewards amounting to nearly HK$10 million, put up by police as early as 1997, remain on offer with more than 20 culprits still on the run. The police website lists 25 rewards amounting to HK$9.95 million for killers, robbers and acid throwers.

The stolen property includes dozens of watches, about 200 Canadian maple leaf gold coins and jewellery.
The second-largest reward, HK$800,000, is for information leading to the arrests of four Wo Shing Wo triad members wanted over the death of Lee Tai-lung, head of the Tsim Sha Tsui faction of the Sun Yee On triad.
Lee, 41, was rammed by a car outside the Kowloon Shangri-La Hotel in Tsim Sha Tsui in August 2009 before being hacked to death.
The third biggest reward is H$500,000 for the recovery of a 16.83-carat emerald ring worth HK$12.2 million that vanished in seven minutes after being left in a washroom at the Four Seasons Hotel in Central in September 2011. It is owned by Caroline Scheufele, co-president of the Swiss luxury watch and jewellery company Chopard.
