The Central Bureau of Investigation (CBI), in its chargesheet, said the 1994 ISRO espionage case, in which former space scientist Nambi Narayanan was falsely implicated, was allegedly created by a then special branch officer of Kerala police to justify his illegal detention of a Maldivian woman in India after she spurned his advances. The central probe agency filed a chargesheet in the last week of June but became public on Wednesday against five former police officers for allegedly implicating Narayanan and five others, including two Maldivian women, in the espionage case.
