According to reports, the schoolgirl was lured into a private spot when a man offered her a present.
Once he had her alone, the man subjected the 13-year-old to a horrifying sexual assault.
The teenager, in a desperate and twisted act of revenge, tracked down her rapist’s young son.
When she spotted the 5-year-old playing alone near his home in Aligarh, she launched a vicious attack.
It is thought that she strangled the child and used his bricks to smash his head in, before cutting it off at the neck.
After an extensive police search, officers found the little boy’s burned body hidden under a pile of rubble.
Speaking to The Indian Express, Officer Sansar Singh explained: “[The girl] said she killed the boy because she had been raped by his father.
“She had not filed any complaint before her arrest.”
The teenager, alleged to be a drug addict, has been charged with murder and sent to a juvenile ahead of her next court appearance.
A medical examination has proven that she was the victim of sexual assault, and the boy’s father has been charged with rape.
