Six explosions took place in Yaring, Yarang and Sai Buri districts on Sunday morning. Two of them were seen riding two road bikes wearing cycling outfits in tambon Yarang while another suspected perpetrator drove a motorcycle behind them. According to the source, the first blast at the bin took place at 8.30am. The bicycle bombings, which happened 15 minutes later, caused two security officers, who came to inspect the first blast, to suffer from blast-induced tinnitus. Officers believe the bomb may have been put there on Sunday, when a string of blasts took place, but it malfunctioned.
