KUALA LUMPUR, May 22 — Police are looking for a doctor believed to be part of a drug syndicate after a raid on a double-storey house in Taman Tun Dr Ismail here on Wednesday revealed the possibility of a laboratory.

They arrested four men and a woman who were processing drugs.

City police chief Datuk Tajuddin Md Isa said the suspects under interrogation mentioned that a doctor was part of the syndicate.

“We believe the doctor and an accomplice left the house before the raid,” he said.

“We can’t reveal much about the doctor as it may hamper investigations but we are confident he will be arrested soon.”

Tajuddin said police uncovered the drug lab after being tipped off that drugs were being sold in Brickfields.

“Twenty-seven drug addicts were caught in Brickfields recently and they led us to the arrest of two men in Bangsar who were believed to be ganja suppliers,” he said.

“The two men in their 30s told us they were getting their supply from a drug lab operated by a syndicate.”

Tajuddin said the two men had police records for gangsterism. 

“In the past six months, we believe they raked in thousands of ringgit as they were supplying drugs in bulk to distributors from within and outside the Klang Valley,” he said.

Police found several notebooks listing transactions carried out with “customers” from different states as well as a “recipe book’’ to make syabu.

They also seized various types of drugs, including 1.3kg of syabu, 430g of ketamine, 3.6kg of ganja and 23kg of drug powder, worth RM277,000.
