Two M 79 grenades were fired into the rally site of the People’s Democratic Reform Committee at the Sala Chalermprakiat pavillion in Chonbui Muang district where 2,000 demonstrators were attending but both missed the target.
The two grenades landed at the office of the Tambon Bangsai Municipality at about 9.30 p.m Friday night damaging glass panes and cars parked nearby.
EOD police said the perpetrators fired the grenades from a running vehicle and therefore missed the crowd a distance.
If the grenades landed in the rally site, casualties would be high.
Activist entertainers Yong Lookyee and Japong Sarakam were speakers on the stage when the grenades were fired.
