33,000 pills suspected to contain the drug Hagigat were confiscated Sunday night when detectives from the Tel Aviv Police controlled substances division searched a Tel Aviv apartment.
The detectives noticed two scooter drivers exchanging envelopes and consequently tailed one of them to the house where the pills were stashed.
During the investigation, the scooter drivers were found to be brothers and the envelope they exchanged contained 200 suspicious pills.
A digital scale and paper envelopes were also found in the brothers' house. Police brought the two to the Tel Aviv District Court for a remand extension hearing on Monday.
