"Some youths are involved with drug selling after purchasing those from online platforms," said Dhaka Metropolitan Police's (DMP) Deputy Commissioner (Motijheel Division) Abdul Ahad in a briefing at Paltan police station.
"During the primary interrogation, the arrestees informed police that another 13-14 groups are still active in LSD selling in the capital," said the DC, adding, "LSD has been available in the country for past few years, but the matter came to light after death of a Dhaka University student recently."
"They collect LSD from sources in abroad, mostly different European countries, through luggage parties, postal and courier services. They also sell hemp and methamphetamine," DC Ahad added.
Police arrested three students of two private universities along with LSD drug from Dhanmondi on Wednesday. Later, five more youths were arrested with the hallucinogenic drug from Khilgaon and Baridhara areas on Saturday night.

LSD (lysergic acid diethylamide), first synthesized in 1938, is an extremely potent hallucinogen. It is synthetically made from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains. It is so potent its doses tend to be in the microgram (mcg) range.
