SHENZHEN: The city's public security bureau yesterday handed over 30 drug users to Hong Kong police as part of an ongoing bid to crack down on cross-border drug crimes.

The 29 men and one woman, aged 22 to 56, were caught earlier this month taking ketamine and ecstasy during police raids on four entertainment sites in Shenzhen in South China's Guangdong Province.

Since their arrest, the 30 have been kept in police custody or at drug rehabilitation units.
