A 41-year-old woman created a scare after she breached layers of security to gain entry into the headquarters of Indian Space Research Organisation here using a fake identity before being arrested. Presenting the fake ID, Buela M Sam from Ahmedabad stayed at the ISRO Satellite Centre guest-house at Jeevanbheema Nagar here for two days from September 19. Two days later, she also gained entry into the high- security "Anthariksh Bhavan".

ISRO sources said she may not have swiped her card to enter as requried. In all probability, she may have just waved her card to the Central Industrial Security Force (CISF) personnel, who apparently allowed her in around 11 am on September 21. CISF personnel questioned her but her answers were totally inconsistent. Intelligence bureau sleuths questioned her the next day but could not get consistent response from her.

Her fake card said she worked at "ISRO Mangalore", while the space agency has no unit there. Inquiries revealed that that she is from Ahmedabad, from where her husband, Alexander, was summoned and questioned. During interrogation, he claimed that his wife is "mentally ill" and the family was unaware that she had travelled to Bangalore, the sources said.
