The victim had gone out with the accused in a car in which she was later raped, said a police official.
The victim’s family members came to know of the sexual assault when the accused, along with his four friends, drove the victim down to her house in the same area after the crime, the police sources said.
The accused and his friends had a brief altercation with the victim’s neighbours while they were dropping her, the police sources said.
While Anish managed to escape, his four friends were trashed by the area residents. Anish was arrested later by policemen, the sources added.
A rape case against Anish was registered on Sunday evening after the victim’s medical report confirmed rape, police said.
