Authorities had said they were looking for a “woman wearing a black shirt” who video showed standing in front of the prime suspect, but they now believe she is not connected to Monday’s blast, which killed least 20 people and wounded more than 120.
Some reports said 36 firefighters are missing since the blasts late Wednesday that killed at least 56 people and wounded more than 720 people in what is described as one of China’s worst industrial disasters.
The chief suspect is “an unnamed male foreigner”, according to an arrest warrant issued Wednesday by a Thai court. Authorities appear to have few solid leads and have given confusing and sometimes contradictory statements on the investigation.
Initial report suggests that at least nine people were injured in the explosion in the Shandong province city of Zibo, So far no news of any death has been reported from the site, according to the official Xinhua News Agency.
The authorities believe bomb blasts at the Erawan shrine and Sathorn Bridge in Bangkok this week were aimed at discrediting the military government, national police chief General Somyot Poompanmuang has said.
Thai police say they have questioned and freed one man who handed himself in after being seen on CCTV at the Bangkok shrine moments before a deadly bomb blast, but the prime suspect remains at large.
The bombing involved at least 10 people and was planned a month in advance, Reuters reported, citing Thai police chief Somyot Poompanmoung. It accuses an “unnamed foreigner” of conspiracy to commit “premeditated murder” and weapons offences.
Police officials told reporters Thursday that authorities believed those behind the blast must have been planned it in advance, maybe a month ahead of time, and likely included a site inspection team, bomb makers, bombers and an escape team.
Yesterday, a manhunt was underway for a man, wearing a yellow t-shirt and heavy-framed glasses, seen in CCTV footage apparently depositing a black rucksack at the scene before vanishing into the crowd only minutes before the explosion.
