A police team comprising cops from Andhra Pradesh and Tamil Nadu have surrounded the men, who are believed to be heavily armed. Teams from Andhra Pradesh's anti-terror force, Organisation To Counter Terrorist Operations or OCTOPUS, have been rushed to the spot to assist the police, officials said.
According to news agency IANS, a Tamil Nadu police party had come under fire by the men today when they were conducting a search operation in a residential area in Puttur town, which is 30 km from the temple town of Tirupati and close to Tamil Nadu.
Police sources say the men are suspected to be behind the killing of Bharatiya Janata Party's Tamil Nadu unit general secretary V Ramesh, who was attacked fatally with sharp-edged weapons near his house in July.
