Days after mid-day published an investigation on the illegal Aadhaar centres operational in Thane, the Crime Branch has started investigating them. Deputy Commissioner of Police (Crime) Dipak Deoraj told mid-day that the Thane police have written a letter to the Collector, asking whether the private Aadhaar centres are illegal.

The Collector's office decides the legality of the centres and hence will inform the police about the same.
