Police said that the incident took place last evening when the girl, a student of Std VII, was alone at her home.
The four accused, who live in same neighbourhood as the victim, went to her residence on the pretext of taking a textbook from her. However, once inside, they molested her.
The victim said in her complaint that they even gagged her and attempted to rape her. She, however, fought off the four, who then fled, police said.
All the accused were picked up from the same area, police said, adding that further inquiries are on in the matter.
