Authorities are continuing the hunt for the yellow T-shirt clad suspect connected to the deadly Bangkok bomb blast that killed 21 people and injured more than 120 others. The search for the Bangkok bomb blast suspect took place Tuesday following the harrowing incident in a popular shrine in Bangkok.

Later during the day, a second explosive was thrown from the Thai capital's bridge.

On Tuesday, Thailand's junta leader announced that security forces had identified the Bangkok bomb blast suspect, who appeared to have targeted foreigners at the Hindu shrine. Among the 21 confirmed dead were Hong Kong, Chinese, Malaysian and Singaporean nationals.

According to Police Chief Somyot Pumpanmuang of Thailand, the surveillance video of the Bangkok bomb blast Monday showed a man carrying a backpack near the scene of the bombing. Following the blast, the man was shown without the bag

"That man was carrying a backpack and walked past the scene at the time of the incident. But we need to look at the before and after [security] footage to see if there is a link," said Somyot.

Witnesses said the scene was horrific as body parts were seen scattered around the site of the Bangkok bomb blast, which also blasted windows as well as burned motorcycles, according to NBC News.

"It was like a meat market," said paramedic Marko Cunningham, adding that the Bangkok bomb blast created a 6-foot-wide crater.

In a televised address, Thai Prime Minister Prayut Chan-ocha said he promises to bring those responsible to justice.

"It is apparent that there are active individuals or groups that harbor the intention to damage Thailand," he said, adding that the suspected terrorists wanted to damage the country's "economy and tourism."

Prayut also believed the Bangkok bomb blast suspect to be from an "anti-goernment group based in Thailand's northeast," considered the origin of the Red Shirt movement which opposes the military junta, according to The Hindustan Times.

Meanwhile, on Tuesday, a man also threw a small explosive from a central Bangkok bridge. According to Reuters, the bomb fell into a canal thus caused no harm to anyone.

On Monday, the State Department said that Thailand authorities are already investigating the Bangkok bomb blast and that so far, they have not asked assistance from U.S. officials.

In less than 24 hours following the Bangkok bomb blast, there were already reports of cancellations into the country. Hong Kong has already issued a "red alert" travel advisory, which warns against non-essential travel.

"This will have an impact on tourism," said Finance Minister Sommai Phasee. "But it's difficult to estimate the impact on GDP because we are in the off-season now. We will have to wait until October for a clearer impact. We are praying that tourists will forget about this incident by then."
