The UN cites the story of Tarrem Kosa who spoke to Human Rights Watch (HRW) about how the Naxalites came to recruit him when he was in class eight.
"I was studying in an ashram school (government-run residential school) when Naxalites came to my hostel. They took four students from my school, but after 10-12 km the other three were sent away, and only I was kept," he told HRW.
According to the report, Kosa who was 13 or 14 at the time, was trained to use bows and arrows, and then he was given a rifle and trained to plant bombs.
In India, nearly 300 schools were reportedly blown up by Maoists between 2006 and 2009, according to the report. These include, 18 in the first half of 2009 in Jharkhand and Bihar and 50 in those two states in the whole of 2009.
