Dentist Rajesh Talwar, accused of murdering his daughter Aarushi, was on Tuesday  taken to his house by the CBI to understand the sequence of crime even as the investigating agency was preparing grounds to get the extension of his one-day remand. Talwar was taken to his Sector 25 house in Noida in the early hours to understand the sequence of crime, sources said.

The agency will produce the dentist before the designated court in Ghaziabad today  where it will press for his further custody as his questioning was not completed.

The CBI had taken the custody of Talwar for a day. The investigating agency had found loopholes in the probe carried out by the UP Police till now. CBI investigators who examined the crime scene and questioned witnesses said the UP police had not picked blood samples or the finger prints properly from the crime scene.

Senior CBI officials, probing the case, while remaining silent on the investigations, said the case could have been solved in less than 24 hours if the probe had been carried out properly by UP police.
