Superintendent of Police Durai placed SI Shankar, who was arrested on October 7, under suspension.
The action followed a directive by the Madras High Court bench at Madurai on a petition filed by an advocate seeking a CBI probe into the alleged gangrape of the 17-year-old girl. The 55-year-old policeman was among the accused in the case, in which the court had directed police to file an Action Taken Report.
The girl's relative had lodged a complaint with the SP.
The petitioner had alleged that police had forced the woman to file a complaint charging only the father and brother with raping the girl, omitting any allegations against others.
He had also submitted that the girl had undergone forced abortion many times.
