Muscat: The Royal Oman Police (ROP) have seized another big consignment of heroin with the arrest of two expatriates from an Asian country.

“The two accused of Asian nationality were in possession of 450 capsules containing 3.7 kilogrammes of heroin at the time of their arrest,” a police spokesman said.

The Directorate of Narcotic Control acted on information that the two suspects were in possession of a large quantity of narcotics at their hideout in Ibri in Dhahirah region.

“After making thorough investigations, the raid was carried out and accused were caught red-handed,” the spokesman said, adding that further investigations were on to uncover a suspected network of drug traffickers.

Last week, police had caught three Asians and seized a record amount of narcotics. The three accused were caught with 463 heroin capsules that weighed in at nearly 11kg.

Meanwhile, in an ongoing crackdown against drug smugglers and addicts, police in the Dhofar region also caught traffickers trying to smuggle ‘khat’, a stimulant drug derived from a shrub (catha edulis), into Oman.

One suspect was arrested by the ROP in Thumrait with 300 packets of khat while another was caught with 112 packets of the same substance.

The police have urge residents and citizens to report any drug-related activities by calling 1444 or 9999.
