Police have obtained seven new search warrants in the Project Brazen 2 investigation, lawyers for CTV confirm.

That's the probe involving Mayor Rob Ford.

A provincial court judge granted the new warrants over the last four months.

They reportedly include authorizations for police to obtain call records from four different wireless providers.

It is unknown what police are looking for with the warrants.

The unsealed documents will only be made available to Crown attorneys, who will then determine whether any censoring is needed before the materials are released publicly.
