Taking a serious note of the ?unpardonable? act of frisking of former President A P J Abdul Kalam at the Indira Gandhi International Airport, the government has slapped a showcause notice to the US-based Continental Airlines for violating guidelines. Meanwhile, as per the FIR, on April 21, 2009, Abdul Kalam was travelling by Continental Airlines Flight from New Delhi to New York. As he proceeded towards the aircraft, the staff of the Continental Airlines carried out frisking of Azad even as the CISF personnel pointed out that he was exempted from such checks. An enquiry was ordered into the matter which established that the staff had wrongfully, under the direction of their security-in-charge, country director and station manager, carried out pre-embarkation body check of Azad. ?Not only the preliminary inquiry has been ordered but we also have a preliminary report on the basis of which Continental Airlines has been issued a show cause notice why action for willful violation should not be taken,? civil aviation minister Praful Patel said in the Rajya Sabha on Tuesday.
