A bench of justices R M Lodha and Shiva Kirti Singh disposed of a PIL with the direction to CBI to conduct a speedy investigation in a "time-bound" manner in the case after it was told that Bihar government has already issued a notification recommending the probe by the agency.
The girl, a class VII student of St. Xavier Public School in Muzaffarpur in the state, had gone missing from her house located in Ghirnipokhar locality under Town police station area on September 18 last year.
Prachi Mishra, the counsel for Kumar, has also filed some additional documents to support the plea that there was "serious lacunae" in the investigation carried out so far by the state police and the CID.
The PIl alleged the investigation has been poor as no statement of the complainants and other important witnesses have been recorded and moreover, no role has been ascribed to the three accused persons named in the charge sheet.
The petitioners alleged they fear for their lives for raising the case of the girl.
