As Hyderabad is the common capital of both the states for ten years, the secretariat of erstwhile Andhra Pradesh has been divided into two from June 2 for the administrative purpose.
While Telangana government has been allocated A, B, C and D blocks, the Andhra Pradesh government is given J, K, L, H-south and north blocks.
The barricades erected overnight separated blocks that constituted Telangana secretariat from the Andhra secretariat.
A large number of personnel belonging to the central security forces are deployed at these barricades. The decision to physically divide the secretariat was taken by the government, said a senior police official.
VB Kamalasan Reddy, DCP (Central Zone) said that barricades have been put up for security reasons, besides limiting the flow of visitors' movement between the two zones.
"It is a government order to put up barricades for security reasons. Visitors are moving from one side to another without any authorisation. Some visitors obtain (entry) pass from one gate and moving into other zone," Reddy said.
However, employees of the Andhra Pradesh Secretariat have expressed disappointment over the arrangements.
"Employees were not consulted before erecting barricades. The move sends wrong signal that situation in the Secretariat is not congenial," said AP Secretariat Employees Association president Murali Krishna.
