The fight, which broke out around 8am, reportedly came after some students and graduates, who had been at a reunion party since Friday night and were possibly drunk, crossed the street to the stadium and got into a fistfight with a group of red-shirts outside the stadium, said Pathumwan police station chief Colonel Paisarn Luasomboon.
The fight, followed by the sounds of gunfire and explosions from the school, prompted many red-shirts to run for cover, while the students shouted abuse at them from inside the college.
Paisarn commented that the explosions from the college had been firecrackers lit by the students.
The fight, which caused traffic on Rama I Road to be heavily congested, prompted Paisarn to deploy 200 officers in front of the college to prevent students from clashing with the red-shirts again.
With security in place, the Thaksin supporters occupied most of the roofed seats inside the National Stadium by noon.
They were spooked, however, when an explosion was heard in front of the stadium at 3pm, but nobody was injured. Paisarn later commented that someone might have thrown a giant cracker inside a plastic bottle from a passing car and police would process the scene in detail later.
With many people attending the event, which was scheduled to last until late last night, city motorists were advised to avoid the area around the stadium on Rama 1 Road, Phayathai Road, Rama 4 Road, Sam Yan Road and Sathorn Road.
