Acting on a tip-off about banned substance being sold in Chunabhatti in the eastern part of the city, sleuths from the ANC's Bandra unit laid a trap and arrested a man, a police official said.
The man was found in possession of 60gm of mephedrone, or meow meow, worth Rs 1.20 lakh, the official said.
The accused, Sarfaraj Sabirali Khan, is a resident of Kurla. He has been booked under relevant sections of the Narcotic Drugs and Psychotropic Substances Act, he added.
