A four-year-old girl was sexually assaulted by a 19-year-old youth in her building on Tuesday afternoon.

The accused, a relative of the landlord of the building, lived on the ground floor while the victim’s family stayed upstairs. A relative of the victim told The Hindu that the girl had returned from school. As her mother had not come home yet, the child went to an anganwadi near the house and later returned home.

However, the girl, after returning home, was downstairs for a fairly long time. “Her mother was not worried as she knows the people downstairs. But when she came home, she was crying and was unable to walk. When we enquired with her, she told us what happened and we lodged a complaint with the police,” the relative said.

The family claimed that a medical examination showed that the victim’s private parts had been injured. The victim’s family said that they had moved into the building a year ago.

The victim’s family said that after knowing about he alleged abuse, the accused’s family handed him over to the police.

Some local residents staged a protest against the alleged incident.

The Chandra Layout police have taken the boy into custody.
