A doctor from Shivaji Nagar in Mumbai was arrested for allegedly making fake documents of a baby boy earlier to facilitate an illegal adoption, Crime Branch officials said on Sunday.

"One of the kin of the family that adopted the infant boy approached Mumbai police claiming the papers, including birth certificate, seem to be fake. A probe zeroed in on a Shivaji Nagar based doctor, who had told the couple the child was born in his hospital, despite the birth taking place in Rajasthan," the official said.
