Andhra Pradesh Police have made heavy security arrangements in Hyderabad in view of the 'Chalo assembly' protest to be held today by deploying about 10,000 police personnel from the state and 20 companies from the central para-military forces.
After refusing permission for the protest, the police on Thursday started checking vehicles at entry points to foil the attempts of the protesters to get into the city.
The police have also intensified surveillance following inputs that Maoists might mix up with the protesters.
Scores of pro-Telangana activists, including leaders of different political parties, have already been taken into preventive custody.
Police have imposed prohibitory orders under section 144 CrPC banning assembly of five or more persons in the limits of Hyderabad and Cyberabad Police Commissionerates which will be in force till 6am on June 15.
Police have made it clear that participation in the 'Chalo assembly' will be "illegal" and advised students and government employees to stay away from the agitation.
"Some anti-social elements under the guise of agitators are planning to cause harm to private and public properties and trying to create disturbances affecting public peace and order in Hyderabad," city police commissioner Anurag Sharma has said.
In Mahabubnagar district, over 2,000 pro-Telangana activists were rounded up, Superintendent of Police Narendra Kumar said.
Elaborate security arrangements have been made in the city to ensure that the ongoing session of the assembly passes off smoothly and 17 check-posts set up in different parts of the city to keep a tab on vehicles and suspects.
Besides, huge police force has been deployed within 2-km radius of the assembly premises. While over 6,000 police personnel have been deployed in Hyderabad, over 3,000 police personnel are on duty at Cyberabad.
Traffic police also announced restrictions on different routes leading to the assembly besides blocking flyovers and appealed to the public to use diverted routes.
Meanwhile, Andhra Pradesh State Road Transport Corporation (APSRTC) officials said they will be re-organising the routes of the buses plying in the region after holding consultations with police while the South Central Railway (SCR) has announced cancellation/partial cancellation of some of the passenger and local train services as a precautionary measure, officials told PTI.
"Security has been strengthened at vulnerable stations and trains by deploying more number of RPF and GRP personnel. We have also opened emergency control rooms at Rail Nilayam to monitor the situation round-the-clock and our officials will be in touch with state police," SCR chief public relations officer K Sambasiva Rao said.
The government has already declared a holiday for schools in Hyderabad for June 14.
Earlier on Thursday, pro-Telangana students clashed with police in Osmania University campus for the second consecutive day, demanding that they be allowed to take out a rally towards the state assembly.
Protesting students pelted stones at the police who retaliated by firing teargas shells.
A report from Medak district said more than 1,100 pro-Telangana activists were bound over and 180 taken into custody by police in view of the 'Chalo Assembly' call.
Meanwhile, Telangana leaders said they would participate in 'Chalo assembly' programme saying police cases are not new for them and they will not yield to any pressure.
