New Delhi: A man has been arrested for allegedly raping a 10-year-old mentally-ill girl for almost a week at outer Delhi's Mianwali Nagar, the police said on Thursday.
The accused was the owner of the house in which the victim stayed with her family members as tenants, they added.
The incident was reported to the police on Wednesday. The brother of the girl caught the accused forcing himself on his sister and informed the police.
There was a change in the behaviour of the mentally-ill girl of late, the family members told the police. When her brother returned home on Wednesday, the girl was not there.
