The girl stated in her complaint that she was abducted and raped on May 25 by two people and later taken to the MLA's house in Ratnipur, the SP said.
She further alleged that for four months she had been held hostage and raped so that she would not tell anyone about the incidents, but she somehow managed to escape on Sunday, Kakkad said.
The SP said the matter is being investigated and FIR would be lodged only after completion of the investigations.
Gautam, who is MLA from Auraiya Sadar (reserved), dismissed the allegations saying he was being "framed".
