About 100 people were arrested at two illegal bars on Hong Kong Island and in the New Territories during police raids on the weekend.

At 7am on Saturday, officers from the anti-triad squad at the Hong Kong Island Regional Police Headquarters and Central District Police Station raided an illegal bar at 12-13 Lei Yuen Street East in Central, Sing Tao Daily reported.

A Nepalese man was arrested for allegedly selling liquor without a license and possession of unlicensed liquor for sale.

Some 23 men and 33 women aged between 25 and 54, mainly Filipinos and Nepalese, were arrested for allegedly drinking in an unlicensed venue.

Police confiscated 700 bottles of alcohol with a market value of HK$20,000 (US$2,548) and HK$2,000 cash in the 600-square-feet illegal bar.

Police said they are investigating the background of the bar and did not rule out the possibility that a triad organization was involved in its operation.

It was understood that police have busted illegal bars in the same building over the past year.

Meanwhile, another team of officers from the anti-triad squad and a special duty unit at the Yuen Long Police Station raided a flat in an industrial building on On Lok Road in Yuen Long in the New Territories.

The flat was said to have been rebuilt as an illegal bar which had been in business for two months and controlled by a triad gang.

Some 610 bottles of beer worth around HK$21,000 and HK$5,700 in cash were confiscated.

A 35-year-old Hong Kong man said to be the in charge of the bar and 24 men and 18 women aged between 29 to 72, mainly from the mainland China, were arrested.
