At his home in a narrow lane in Velacherry in south Chennai, a former intelligence officer is taking tuitions to ensure that his children have food and a roof over their heads. S Natarajan was sacked from the Research and Analysis Wing or RAW in 2009, after 25 years of service, on what he says are fake charges. The agency has refused to take him back even after the Central Administrative Tribunal struck down his termination in February, and ordered his reinstatement within four weeks.
