The incident has also brought under scanner the guest records of Assam Bhavan and Arunachal Bhavan in Delhi, where the prime suspect in the case - who is known to the doctor - is believed to have stayed, a senior police official said.
Multiple teams are working on the case, with one each been sent to Rajasthan, Haryana and Arunachal Pradesh. Today, the five-member team, which was already in Arunachal Pradesh since September 30, was sent to Dibrugarh to get the entire story. However, the doctor has refused to talk to the team, said the senior official.
On September 25, his wife called up the police and reported that he was untraceable for the past two days. A police team was sent to the central Delhi hotel where the doctor had lodged himself and it turned out that he was last seen on September 23 evening. A missing report was registered immediately.
