Customs officers arrested a youth and seized about 38 kilograms of suspected ketamine, with a market value of about $4.8 million, in San Tin, Lok Ma Chau yesterday.

They stopped the man in Wing Ping Tsuen and found 10kg of the drug on him, then seized another 27kg and packaging tools from a nearby residential unit.

The 18-year-old was charged with obstructing Customs officers and trafficking in a dangerous drug. He will appear at Shatin Magistrates' Courts tomorrow.
