The students were rallying inside the university compound attacking the ignorance of the Hua Mark police to probe into the shooting which left one of their colleagues shot dead, and over 50 injured from gunshot wounds and small bomb explosions thrown on November 30 and December 1 during the rally of the red-shirt supporters of the government at Rajamangala stadium.
The students said so far they did not receive any progress in the probe and doubted the police might not take the case seriously.
They gave the Hua Mark police chief to give them a clear answer on the case within two hours, otherwise they would march out of the university to the Hua Mark police station.
