BANGKOK (UPDATED) - An explosive device wounded 28 anti-government protesters in the Thai capital on Friday and other violence was reported after several days of relative calm when the movement appeared to be running out of steam.
Police said the device was thrown at protesters marching with their leader, Suthep Thaugsuban, near Chulalongkorn University in the city centre and the estimate of the number of injured came from the Erawan Medical Center, which monitors Bangkok hospitals.
Protesters broke into a building under construction near MBK shopping mall in the capital, to search for those responsible for throwing the device.
One Bangkok resident said he saw someone he believed was responsible run into the construction site and called for police to help them search.
"The suspect was running up into the building and I shouted for security guards to capture that guy. I believe that he is still in the building," Pheeradej said.
It was not immediately clear who was responsible. None of those who sustained injuries were believed to be life-threatening.
The political unrest flared in November and escalated January 13 when the demonstrators led by former opposition politician Suthep brought parts of the capital to a standstill and forced many ministries to close.
