Tight security arrangements have been made in Andhra Pradesh on the eve of the Republic Day.
Following an advisory from the central government that terrorists might carry out attacks on the Republic Day, the police have stepped up security at all vital installations in the state.
The capital city of Hyderabad, which has witnessed three terror attacks since May last year, is on high alert to foil any attempt by terrorists to disrupt the Republic Day celebrations.
Large number of policemen was deployed around the state secretariat, historic monuments, public places, defence laboratories and other vital installations.
The security personnel have started carrying out large-scale checking of vehicles and frisking of people in different parts of the city. Airports, railway and bus stations are also under the tight vigil of the police.
The police teams have also conducted surprise checks at lodges in Hyderabad and its twin city of Secunderabad since last night to inquire about those arriving from outside and staying there.
The security personnel have also made tight security arrangements at Parade Grounds, Secunderabad, where the main official function will be held. State governor ND Tiwari will unfurl the national flag and review the parade.
Security agencies have taken the grounds in their control and dog squads are frequently carrying out checks to ensure that no explosive is planted.
Police Commissioner D Prasada Rao, who assumed charge on Monday, visited the historic Mecca Masjid and some other places in the city to review the security arrangements.
A bomb blast during Friday prayers at the 17th century mosque on May 18 last year had killed nine people. In August, two near simultaneous blasts at a public park and an eatery had claimed the lives of 44 people.
These were the worst terror attacks in the city's history and police blamed the terror groups based in Pakistan and Bangladesh for the blasts.
