Acting on a tip-off, the Amboli police laid a trap on Sunday and nabbed the duo when they arrived on Veera Desai road on a motorcycle, he said.
The value of the prohibited drug was estimated to be around Rs 40 lakh, he said.
Nayak said that Imran Ansari's arrest was significant as he was believed to be among the biggest drug dealers in the western suburbs.
The two were booked under relevant provisions of the Narcotic Drugs and Psychotropic Substances (NDPS) Act, he added.
