High alert has been sounded in the city following the recent recovery of a powerful bomb in Hyderabad, ahead of the festival of Diwali.
The police have intensified search and frisking operation thereafter and appealed to the people to be vigilant. Security has been beefed up at vital installations, places of worship and shopping malls.
Hyderabad is home to a number of scientific institutions, defence laboratories and other strategically significant organisations.
The bomb, put in a plastic box, contained Improvised Explosive Devices (IEDs) and it was detected near a railway track at Chandanagar on the city outskirts by a sweeper four days ago. It was promptly defused.
This is the first time, the police have recovered a bomb at a public place after the deadly Mecca Masjid blast on May 18 and twin blasts on August 25, though there were hundreds of hoax calls.
The city was on high alert following a warning by intelligence agencies last month about the presence of suicide bombers.
Another major worry for the police is the large quantity of RDX reportedly smuggled into the city which remained undetected even after two months. Efforts were on to trace the missing RDX.
The police came to know about the smuggled RDX after one of the suspects arrested in connection with the terror blasts disclosed information about it.
