BANGKOK (AFX) - Three people were slightly injured when a small bomb exploded in the courtyard of the Bangkok office building that houses the justice ministry, police said.
The bomb went off after midday at a food stall in the courtyard of the Software Park building.
The blast occurred just below the second-floor office of the country's leading forensics expert, pathologist Porntip Rojanasunan.
Police said the bomb caused little damage to the building, but destroyed part of the wall surrounding the property.
Prime Minister Thaksin Shinawatra said a special team will investigate the bomb attack but declined to give any details.
'It's really bad. I will ask my intelligence team to investigate. At this moment, I don't know what caused (the explosion) but of course, I will pay special attention,' he said.
He declined to speculate on the motive for the bombing, or to link it to unrest in the Muslim-majority south.
