Police Gen. Pongsapat Pongcharoen said on Monday that officials are suspending the law because they see no imminent threats.

The law was invoked in February mainly to control protests near the prime minister's office.

The act allows police to impose curfews and restrictions on gatherings and makes it easier to mobilize the military.

Thailand has been wracked by unrest since a 2006 coup ousted Prime Minister Thaksin Shinawatra.

Anti-Thaksin demonstrators occupied the prime minister's office in 2008 and seized Bangkok's airports. Last year, pro-Thaksin protesters besieged parts of Bangkok. The standoff deteriorated into violence that killed 90 people.
