Accompanied by central forces, the Enforcement Directorate teams conducted the raids at Salt Lake, Kaikhali, Mirza Galib Street, Howrah and a few other places, he said.
The ones who are being questioned include businessmen and people closely related to those earlier arrested in the scam, he said.
"These raids are connected to the ration distribution scam. We have got information about the involvement of these people after questioning those who have already been arrested,” the Enforcement Directorateofficial told PTI.
The probe agency has arrested a state minister and a TMC leader, among others, for their alleged involvement in irregularities in ration distribution in West Bengal.
