In a bid to crack down on illegal transactions in the city following the demonetisation move, the Income Tax (I-T) department has written a letter to the Mumbai commissioner of police to share details regarding such transactions that have taken place recently.

After the CP’s office received the letter on November 19, all police stations have been asked to gather the information and hand it over to the nodal officer of the department, who would then share the details with an officer of the I-T department.
