Saudi police seized more than eight million so-called captagon pills in an operation that also led to the seizure of raw materials for illegal narcotics in Turkey, the interior ministry said on Sunday.

Six men -- three Saudis and three foreigners -- were arrested in the operation which netted 292 million riyals ($77.9 million) worth of illegal drugs, the ministry said in a report on the official news agency SPA.

The drugs were described as 8,351,087 tablets of captagon, the popular name for what is usually some sort of amphetamine, according to international drug trafficking experts.

The ministry did not say when the operation took place but said that information from the investigation passed on to Turkish authorities led to the seizure of 30 tonnes of materials used in producing such pills. -Business24-7
