THIRUVANANTHAPURAM: The parents of the 13-year-old who died in the capital's police quarters under unusual circumstances believe the drug mafia is behind it. The parents claimed that the authorities ignored complaints from numerous parents about drug gang activity on the school premises.

The girl's parents stated that shocking stories of drug deals centred around various schools in the capital have come to light before. To preserve the school's reputation, schools keep such incidents a secret. The investigation team is unable to assert that the drug gang is behind the death since the minor was also sexually abused.

Chemical analysis of the girl's internal organs also revealed the presence of drug pills. The investigative team states that it is still unknown whether the drug was a banned substance or if it was the residue of the medicine given to the child from the hospital.
