Amaravati,  A youth in Andhra Pradesh poured acid into the mouth of a minor girl and slit her throat when she resisted his attempt to sexually assault her.

The shocking incident occurred in a village in SPSR Nellore district on Monday night when the 14-year-old girl, a class 9 student, was alone in her house.
