In a big operation, the Mumbai Police and Brihanmumbai Municipal Corporation busted five allegedly bogus 'senior' doctors operating in the sprawling slums of Govandi-Shivajinagar areas of north-east Mumbai, officials said here on Thursday.

Following a reliable tipoff, police inspector H.M. Nanavare and constable N.B. Sawant investigated the matter discreetly and then informed the BMC Assistant Health Officer of M-East Ward Dr. Priya Koli.
