CBI sources said the agency has got information that several doctors, who studied in the Commonwealth of Independent States (CIS) countries are practising here without fulfilling necessary formalities.
The sources said it also came to light that some of them allegedly colluded with MCI officers, who gave them permission to practice in exchange of illegal gratification even as the doctors did not fulfill necessary parameters.
"When the report came to us, we viewed it with utmost seriousness and today after finalising the FIR, we have carried out nationwide searches," CBI director Ranjit Sinha said.
The sources said agency started a coordinated search operation across the country.
"This is an important case as such people were playing with the lives of patients," Sinha said.
