Saudi security forces have dismantled criminal networks operating in the Riyadh and Hail regions that were trafficking in amphetamine, methamphetamine (known locally as shabu), and medically regulated pills, the Interior Ministry said on Sunday.

The networks were uncovered based on intelligence gathered by relevant authorities within the ministry, a ministry spokesperson said in a statement. A total of 37 individuals were arrested, including 28 Saudi nationals—among them one employee from the Interior Ministry, two from the National Guard, two from the Ministry of Defense, and one from the Ministry of Health.

Also detained were two Ethiopian nationals accused of violating border security laws, five Syrian expatriates, and two Yemenis—one a resident and the other a visitor.

Authorities said all legal procedures had been completed, and the suspects were referred to the Public Prosecution for further investigation.

The Interior Ministry said the announcement underscored the vigilance of Saudi security forces in confronting criminal plots aimed at targeting the kingdom and its youth with narcotics.

It added that authorities would continue to thwart such schemes and take firm action against anyone involved, regardless of their status, to safeguard the security of Saudi Arabia, its citizens, and residents.
