A three-year-old Indian girl is in critical condition after she was allegedly raped by her neighbour in the capital Delhi.

The accused, a 40-year-old security guard who worked in the building the child lived in, has been arrested.
Police found the girl unconscious and rushed her to hospital where she is undergoing surgery.

The incident occurred on Sunday, which was the sixth anniversary of the brutal gang rape of a student on a Delhi bus.

Delhi Women's Commissioner Swati Maliwal said the incident let down the bus rape victim, whose attack saw country-wide protests and a tightening of rape laws.

The girl's parents, who are daily wage labourers, were away when the incident occurred.

The accused allegedly lured the girl with sweets and picked her up from outside her house.
