Indian Space Research Organisation on Wednesday said the arrest of a senior American scientist,who played a key role in the Chandrayaan-1 moon mission,was "no reason for concern" as it had followed all security protocols. The scientist,Stewart David Nozette who has been arrested for alleged espionage in the US,had no access to any "critical" Indian document,ISRO chief spokesperson S Satish said. "All security protocols had been followed," he said adding,any foreign scientist visiting ISRO had to have all the necessary clearance and submit all valid documents. Nozette's visits were restricted to the Mini-Sar,an American scientific instrument that flew on board Chandrayaan spacecraft,he said. National Aeronautics and Space Administration had two instruments on Chandrayaan odyssey. The US Federal Bureau of Investigation on Monday had filed a criminal complaint against Nozette on charge of spying for Israeli intelligence. Nozette had played a key role in Chandrayaan mission in finding evidence of water on the Moon.
