Hyderabad: Reports of bombs being planted on railway tracks near Hyderabad on Saturday morning forced authorities to launch a massive search operation.
But after almost three hours of intensive search by the security forces the bomb threat was declared a hoax.
Authorities stopped 12 trains at various stations in Hyderabad and railway tracks at all entry points to the city are being examined. Some trains have been stopped from entering the city.
The situation in and around Hyderabad has been tense for the past couple of months over the Telangana agitation.
The violent agitation for a separate state of Telangana by bifurcating Andhra Pradesh has led to massive deployment of security personnel in the region, particularly Hyderabad.
Police officials say more than 20,000 security personnel have been deployed around Hyderabad to maintain law and order after Osmania University students and Telangana Joint Action Committee decided to take out a rally demanding the creation of Telangana.
The protestors have also threatened to lay siege to the state Assembly to protest the terms of reference of the Srikrishna Committee.
