On Saturday night, Akhil had committed suicide by consuming a poisonous substance. He died on Sunday morning.
In the suicide note allegedly written by him, Akhil had had named 10 persons, including his newlywed wife, her parents, relatives and four policemen, including an Indian Police Service (IPS) officer.
The IPS officer, a superintendent of police in an adjoining district, has not been booked, while nine persons have been charged with abetment to suicide.
Police said the family had not named the IPS in their police complaint. The aggrieved family members and relatives are alleging that Akhil's wife had lodged two false complaints and the policemen from her community had been harassing Akhil on the pretext of a police investigation.
In an FIR registered last month, the girl had accused Akhil and his family of fabricating a marriage certificate, kidnapping and forceful submission of marriage in the court. In another case lodged last month, she had charged her "husband" of stalking and sexual harassment.
