Police arrested four men for drug trafficking in a disco on Mody Road in Tsim Sha Tsui early this morning.

The men, aged 23 to 37, have been detained after police officers seized psychotropic drugs - including cocaine, ecstasy, "Ng Jai" and ketamine - from one of them. The seized drugs have a street value of about $15,000.

Police said they are taking rigorous efforts to tackle drug abuse, particularly among youths. They will continue their crackdown on drug-related activities.
