New Delhi: A 28-year-old man has been arrested for allegedly raping a minor girl in southeast Delhi's Govindpuri area.

The 7-year-old girl was sexually assaulted a month back but the incident came to light Sunday evening after her brother talked about it to his mother, police said.

The girl was allegedly raped when she was on her way to buy sweets along with her brother, they said.

According to the complaint, the accused stopped the children and gave the girl's brother money to buy chocolates, while he took the girl to a vacant plot and raped her.

When the brother came back, he found his sister crying and she shared her ordeal with him, police said.

The girl did not tell her parents about the incident since the accused had threatened her that he would rape her again if she revealed anything, police said.

The accused, an e-rickshaw driver, was arrested on Saturday and it is being probed whether he had sexually assaulted other children as well, they added.
