The Warangal poice on Saturday arrested the fourth accused in the death case of former Telangana Congress MP Siricilla Rajaiah's daughter-in law Sarika and her three children.
Sana, who is said to be in an illicit relationship with Rajaiah's son Anil Kumar, was arrested by an eight-member police team led by the Hanamkonda ACP in Khammam, late on Saturday night, the Times of India adds.
Last Wednesday, Sarika was burnt to death at the politician's residence in Warangal along with her three children, a day before she was to appear before a Hyderabad criminal court in connection with a case she had filed against her husband and in-laws.
Sarika, a former IBM employee, had filed a petition and registered a case of dowry harassment in April 2014. She had also staged a sit-in outside her father-in-law's house, alleging ill-treatment.
Keeping those incidents in mind, the Warrangal police registered a case of abetment to suicide and cruelty against Sircilla, wife Madhavi and their son Anil and took them into custody.
Sarika and Anil Kumar Sircilla had a 'love marriage' on March 3, 2006 and had a boy in 2008 and twins in 2013. Some years later, Sarika caught her husband Anil cheating on her, a fact that the chargesheet in the February case records.
Sana is expected to be produced in court on Monday.
Meanwhile, the All India Congress Committee suspended Siricilla Rajaiah from the primary membership of the party as Rajaiah is currently under judicial custody, the TOI report adds.
