The Central Industrial Security Force (CISF) personnel guarding New Delhi airport failed to detect a bomb that passed through the numerous security checks present there. The Bureau for Civil Aviation Security (BCAS) had conducted a mock drill at several airports across the nation over the last three months to ensure all security measures are present. And the drill revealed the failure of the men in the force to detect it, as per a Hindustan Times report. According to the report, a BCAS representative in April last, this year, carried hand baggage and it was allowed to go through all security clearances. After the bag cleared the process, the representative revealed that the baggage contained an IED. Meanwhile, CISF claimed that they do all possible effort to identify suspicious objects during scanning and also take action against the staff who fail to perform their duty, said the report.
