The prime accused in the sensational murder of Chittor Mayor Katari Anuradha and her husband K Mohan, Chandrasekhar alias 'Chintoo' surrendered in court on 30 November, nearly two weeks after the brutal killings.
The court initially remanded Chintoo in judicial custody, but later sent him in police remand till 14 December.
"Chintoo surrendered today and the court has remanded him in judicial custody. We filed a petition seeking his custody for questioning and further investigation. The court has granted 14-day police custody," Chittoor SP G Srinivas told PTI.
He said Chintoo will be sent to prison from there the police will take him into custody after completing the formalities.
Chintoo, nephew of Mohan, has been on run since the couple, both TDP leaders, were allegedly shot at and stabbed to death by at least six persons in the office of Chittoor Municipal Corporation on 17 November.
With Chintoo turning in himself, the number of people arrested by the police so far has reached four.
Out of total 11 accused in the case, police had arrested Venkatachalapathi, a native of Karnataka, Jaiprakash Reddy and Manjunath, both from AP.
A case was already registered under charges of murder and other relevant sections of the IPC and under Arms Act against all the accused including Chintoo.
Police had earlier said that the attack was carried out following a family dispute.
