Police have arrested two Pakistani national suspected of smuggling heroin worth 110 million ringgit ($36 million) into Malaysia.

A federal police statement says Malaysian authorities caught the men with 348 pounds (158 kilograms) of heroin packed together with clothes in boxes at a shop on central Selangor state on Wednesday.

The suspects face a mandatory penalty of death by hanging if convicted of drug trafficking.

Friday's police statement said the drugs were smuggled into Malaysia by sea from Pakistan and could have been intended for sale in neighboring countries. Authorities raided the shop because of a public tip.
