PTI, NEW DELHI: The Crime Branch will take over the probe into the alleged sexual assault of a three-and-a-half-year-old girl at her school last week, police said Tuesday.

The alleged incident occurred last Tuesday in northwest Delhi's Mukherjee Nagar and the next day, a case was registered by the district police under relevant sections of the Protection of Children from Sexual Offenses (POCSO) Act.

The girl's parents also staged a protest outside the school Tuesday demanding an action against the authorities.

A senior officer said the case has been transferred to the Crime Branch since it is a "sensitive one".

According to the police, the family members of the girl were not satisfied with the district police's investigation in the case and wanted an independent probe.
