Police are hunting for four masked robbers who broke into the office at a golf club in Tai Po in the New Territories on Monday.
Four men, aged from 20 to 30 and wearing face-mask beanies, sneaked into the golf club’s office on Ting Kok Road at about 4am and subdued a 38-year-old night-shift security guard surnamed Kwok, Oriental Daily reported.
The four men used wires to tie up Kwok and covered his head with some clothes before ransacking the office.
They took Kwok’s mobile phone and HK$25,000 in cash (US$3,197) and pried open the safe and took away a further HK$60,000 in cash.
The gang then went to the restaurant and souvenir shop and took 11 watches and HK$1,000 in cash.
At around 5am, when the guard could no longer hear any sound, he got the clothes off his head and jumped to a phone on a desk.
As he had been tied up, Kwok had to use his tongue to press 999 and call the police.
Officers arrived and untied him before sending him to hospital for a medical checkup.
Gabriel Choi, president of the Hong Kong Medical Association, said the tongue is a muscular organ of the mouth. If phone buttons are sensitive for touching, it would be possible for a person to use their tongue to press buttons and make a call, Sing Tao Daily reported.
