Thailand police on May 24 lifted the Internal Security Act (ISA) ahead of a general election scheduled for July 3.

The Internal Security Act (ISA) was withdrawn and the body responsible for its implementation, the Centre for Administration of Peace and Order (CAPO), was disbanded on the same day, Police General Pongsapat Pongcharoen, CAPO's deputy director said.

However, Pongsapat said police would step up security in provinces where attacks on politicians had taken place during previous elections and reinforcements would be sent to guard campaign activities by prominent candidates.

The ISA, which was invoked in February, gave the authorities power to impose curfews, operate checkpoints, restrict the movement of protesters and act quickly to break up rallies and arrest demonstrators if violence broke out.

Meanwhile, a bomb blast was triggered in Tak Bai district in Narathiwat province on the same day, killing two policemen and leaving a civilian injured. The attack was blamed on separatists in Southern Thailand. /.
