Acting Penang police chief Alwi Zainal Abidin said the suspects, aged 40 and 62, were believed to have been involved in the distribution of MDMA.

He said the older man was arrested at a house used to process the drugs, and his accomplice was picked up in the same area.

According to Alwi, 150 packets and nine plastic bottles containing MDMA powder, weighing more than 13.4kg, were seized during the raid, as well as two vehicles and cash totalling RM71,220.

“We also seized two ecstasy pills, an Erimin 5 pill, and equipment used to process MDMA,” he said in a statement.

Alwi said the duo had been trafficking drugs since March, involving quantities that were believed to be enough for consumption by up to 100,000 users.

He said both suspects tested positive for drugs and have records for drug-related offences.

They have been remanded until July 23 and are being investigated under Section 39B of the Dangerous Drugs Act 1952 for drug trafficking.
