As the state government last year celebrated June 9 as Child Protection Day, Ghosh was honoured on behalf of the Darjeeling district administration for exemplary work towards child protection. Months after being felicitated by the state government for his contribution towards child protection, the West Bengal CID on Friday arrested Mrinal Ghosh, the Darjeeling district child protection officer , along with a registered medical practitioner – who is also a member of the Darjeeling Child Welfare Committee – for their alleged involvement in the Jalpaiguri child trafficking racket.
