The Mayor, aged around 50, belonged to the ruling Telugu Desam Party (TDP).

Before escaping from the spot, the assailants went into an adjoining room where Anuradha's husband K Mohan, also a senior TDP leader, was sitting. They allegedly shot at him and then stabbed him, Andhra Pradesh Additional Director General of Police (Law and Order) RP Thakur said.
