The two men, Bilal Malik and Panna Ismail, were allegedly involved in the April blast at the BJP office in Bangalore and two murders in Tamil Nadu including the killing of BJP state vice president auditor Ramesh.
The tip-off about their hideout came after the arrest of another suspected terrorist Fakharuddin on Friday near the Tamil Nadu-Andhra Pradesh border. He is the alleged mastermind of a plot hatched to target senior BJP leader LK Advani in Madurai in 2011.
The Tamil Nadu police reached Puttur on Friday night and surrounded the house of the suspected militants. The suspects first stabbed a police inspector and then rushed inside and locked themselves up.
The operation that began around 4 am lasted 10 hours. The suspects were nabbed after a fierce gun battle. Arms and explosives were recovered from them.
The two men are now being held in judicial custody. The Tamil Nadu Police says the arrests are major catches that could lead to the arrests of more operatives in hiding and their future plans. The Tamil Nadu cops would soon seek their custody for further interrogation.
