The Central Bureau of Investigation on Tuesday registered an FIR to probe the suicide of a Tamil Nadu schoolgirl Lavanya.

The schoolgirl’s death has been mired in controversy with allegations of forced conversion against the school in which she was studying and counter-allegations against her family. The agency will probe all angles, said people in the know.

The Madras High Court had ordered a CBI probe into the death of the schoolgirl which was later challenged by the Tamil Nadu government in the Supreme Court. The Apex Court however refused to interfere with the Madras High Court order directing CBI to take up the investigation of the case.

“This court has a duty to render posthumous justice to the child. The foregoing circumstances cumulatively taken will definitely create an impression that the investigation is not proceeding on the right lines. Since a high ranking Minister himself has taken a stand, investigation cannot continue with the State Police. I, therefore, direct the Director, CBI to assign an officer to take over the investigation from the State Police, the Madras High Court had ruled on January 31.

In her dying declaration, the schoolgirl had said that her missionary school had forced her to convert to Christianity and she had been subjected to harassment for refusing to convert.
