A total of 25 people were arrested on suspicion of either working illegally or employing illegal workers in a joint operation by Hong Kong authorities on Wednesday.

At 5am, police, labor and immigration officers conducted raids in Kwun Tong, Wong Tai Sin and Sau Mau Ping districts in Kowloon and Tseung Kwan O in the New Territories and arrested 13 men and 12 women aged from 24 and 72, Sing Tao Daily reported.

Seven of those arrested – five men from India, one woman from Indonesia and one woman from Bangladesh – were asylum seekers who were prohibited from working without a permit, but were found working in restaurants.

Thirteen people were holders of two-way permits from mainland China, and the remaining five were legal Hong Kong residents.

Authorities carried out 559 raids of this kind last year, and 487 illegal workers and 299 employers were arrested, according to figures released by the Immigration Department, Oriental Daily reported.
