Prohibitory orders were clamped in and around the camp of PDP leader Abdul Nasser Madani at Anwarssery near Kollam on Saturday as tension prevailed with a large number of his supporters gathering there anticipating his arrest in connection with the Bangalore serial blasts case.
The district administration imposed restrictions under IPC Section 144 as a Karnataka Police team awaited the nod from the state government to execute the arrest warrant against Madani.
Police lobbed two teargas shells to disperse a crowd in the area. The situation is now under control, police said.
The ban orders were enforced in Mainagapally and nearby Sasthacottah panchyats.
A strong police contingent under Kollam SP Harshita Attalluri is camping in the area. Besides, additional forces of Special Armed Battalion had been sent to the area.
The Karnataka Police team had been camping in Kollam for the last five days to arrest Madani, listed as an accused in the 2008 Bangalore blasts case in which a woman was killed and 20 others injured.
Madani's anticipatory bail plea was rejected by the Karnataka High Court last week.
The PDP leader was also an accused in the 1998 Coimbatore bomb blasts case but was acquitted later. The serial blasts, hours before senior BJP leader L K Advani was to address an election meeting, had left 58 people dead.
