In April 2017 the West Bengal Medical Council tipped of West Bengal CID that several fake doctors were operating in Bengal and requested them investigate. Investigation revealed that most of the arrested fake doctors were attached to some of the well-known hospitals in the state including Kothari Medical,Belle Vue Clinic. One of the prominent fake doctor was Amit Roy Chowdhury a resident of Becharam Chatterjee Road,Behala, who was attached with BNR hospital by giving false medical certificate[8][9][10] By June 2017 over 500 fake doctors had been identified.[11][12][13] Following this several arrests have been made and West Bengal CID along with the state health department are planning to launch an app to spot fake doctors.[14][15] Fake medical institutes and medical colleges were also sealed.[16]
The incident surfaced in November 2016 when evidence emerged detailing how one hospital was selling as many as 65 babies in one month with doctors admitting they have been involved in the trade for decades. Eight months after the case was detected, cops now claim as many as 150 hospitals are involved in this racket. The investigation led to findings related to as many as 10,000 babies changing hands illegally.[17][18][19] Evidence led to orphanages illegally selling babies in America.[20]
During theBlue Whale game outbreak in India, West Bengal CID held awareness campaigns as well as saved an engineering student from risking his life in suicide.[21][22][23]
