'We cannot share anything at present in this connection as the matter is subjudice and also under investigation,' Bhal added.

The sensational case has generated a lot of controversy in the media.

The Noida police had arrested Aarushi's father on suspicion of murder, but as they failed to make any progress, the case was handed over to the CBI. The agency let Rajesh Talwar off, saying there was no evidence against him.

The agency then arrested the dentist's medical assistant Krishna, who was accused of committing the murders with the help of Raj Kumar and Vijay Mandal, both domestic helps in the neighbourhood.

Due to the lack of evidence against the three, the special CBI court in Ghaziabad granted bail to them too.
