Two brothers were among a group of three persons who were arrested by the Customs Anti-Narcotics Unit (CANU) in New Amsterdam, Region Six (East Berbice-Corentyne), on Monday.
CANU said the operation was carried out on Pitt Street, New Amsterdam.
The western half of Pitt Street is considered the main shopping area in the town. However, the eastern half consists of several derelict buildings in one section.
According to CANU, a search was conducted on a building which led to the discovery of a quantity of suspected cannabis and the arrest of three.
The persons arrested are the siblings – a 42-year-old and a 49-year-old – and a 31-year-old woman.
The trio was escorted to CANU Headquarters in the capital city, Georgetown, some 56 miles away along with the suspected narcotic.
The narcotic tested positive for cannabis and weighed approximately 1.2kg, with a street value of $400,000.
Investigations are ongoing.
There have been numerous reports of the use and sale of illegal drugs at the corner of Main and Pitt Streets, New Amsterdam.
Local law enforcement has not been actively trying to make that section of the town more people-friendly, despite its popular use. (G4)
