Acting on a tip-off, ANC sleuths laid a trap on the Jogeshwari-Vikhroli Link Road (JVLR) and arrested Tausif Rafiq Khan (19) and Parveen Kasim Ali Jafari (40) yesterday, he said.
Some 167 kg of ganja was seized from their car, he said.
Khan and Jafari, who are related, are residents of Nalasopara and suburban Sakinaka, respectively.
The investigators were looking for a woman who is suspected to be the kingpin of the drug racket, he said.
Police had seized 500 kg of ganja sourced from Visakhapatnam in another operation recently, the DCP said.
"We suspect that narcotics are being smuggled into the country through Visakhapatnam and brought to Mumbai," he added.
A case under the Narcotic Drugs and Psychotropic Substances Act has been registered, he said.
