Indian police have arrested a senior Maoist rebel blamed for an attack on a police camp in the east of the country last month that killed 25 people, officials said Wednesday.
The man, known by the names Deepak and Venkateswar Reddy, is a close associate of the rebels' top commander Kishenji, West Bengal government official Raj Kanojia told AFP.
A special police team arrested the 45-year-old Reddy late on Tuesday in Kolkata, capital of West Bengal state and one of the many areas across India afflicted by Maoist violence.
"Reddy is a key aide of Maoist leader Kishenji," Kanojia said, adding that intelligence officials had been shadowing him for several days.
"He is an explosives expert and we think he had a major role in the Silda attack that claimed the lives of 24 policemen and a civilian in a western district of West Bengal," Kanojia said.
The official was referring to the February 15 attack in restive Midnapore district, in which around 20 rebels attacked a police camp using guns and landmines.
Police at the time described the armed assault as the worst ever by Maoists on security forces in West Bengal.
The Maoists said they were responding to a large-scale government offensive aimed at flushing the outlawed insurgents from their strongholds.
India's government considers Maoist rebels to be the country's biggest internal security threat.
The leftist insurgents are estimated to number 10,000-20,000 and are predominantly active in a large swathe of the country from the north and east -- called the "Red Corridor."
The Maoist insurgency began as a peasant uprising in 1967 and has now spread to 20 of India's 29 states. They claim to be fighting for the rights of impoverished tribal people and other victims of state violence.
The government has offered talks with the Maoists, but only if they renounce violence. Maoist leader Kishenji last week told local media that the guerrillas were ready for talks if the government suspended their offensive.
New Delhi has acknowledged that the Maoist threat cannot be eradicated by brute force and that steps need to be taken to develop the regions where chronic poverty has fuelled the rebels' ability to recruit new members.
Reddy hails from the southern state of Andhra Pradesh, where the rebels are highly active, the Press Trust of India news agency said, adding that he faces about 50 criminal cases in the state.
