Four people tested positive for drugs after police pursued a motorcycle in the Fuluheh area and stopped the riders.
The individuals were held for five days. Police have not released further details of the chase or the specific substances involved.
The incident is one of several recent drug-related stops involving motorcycles in the Greater Malé region. Officers have increased checks on riders as part of broader efforts against trafficking and possession.
Local reports indicated that the group was travelling together when officers intervened. All four later returned positive results on drug screening.
Authorities continue to monitor known hotspots and respond to public tips about drug activity. No charges have been publicly detailed beyond the initial detention.
Similar enforcement actions have been reported in other parts of the capital in recent days.
