The Tamil Nadu Police have commenced a detailed probe into a baby-selling racket after the intervention of the Madras High Court in a case related to an infant being sold in the Tiruchy district. The police have already arrested four people, including an advocate in the case. The mother of the child was also in custody of the district police. The district police superintendent has told the media persons that the police have commenced a detailed probe into whether the three-month-old baby was alive and whether this was part of a major baby-selling racket in the district and state. Sources in the district police told IANS that the child has changed hands several times and this was leading to a doubt whether the child was alive or had it landed in the hands of a racket.
