According to the media reports, a man picking through trash was seriously hurt early on Friday when a hand grenade left in a dumpster near a Bangkok shopping center exploded.

The Bangkok Post has reported that the bombing was the second this week in the Thai capital. One person was killed Sunday in an explosion at a bus stop.

The scavenger was hospitalized. Police did not release his name.

The grenade's pin had been removed and a rubber band held the trigger mechanism closed, said Maj. Gen. Wichai Sangprapai, chief of Metropolitan Police Division 1. The grenade was hidden in a plastic bag.

The bombings have been carried out by people hoping to prove the government is incapable of maintaining order, Deputy Prime Minister Suthep Thaugsuban has said.

It has also been reported that Bangkok and nine provinces remain under emergency control restrictions after months of demonstrations, riots and violence. (With Inputs from Agencies)
