Unprecedented security was made at the CBI main office in Kothi on Saturday.
Police have taken the extraordinary precaution as they expect that the YSR Congress chief Y S Jagan Mohan Reddy might be brought here for questioning, should the CBI gets his custody as it sought in its petition in the High Court.
Police have regulated vehicular traffic on the busy roads and restricted entries only to persons with proper identities. Police have also set up CC cameras at vantage points so that movements could be tracked. (NSS)
