Thai officials announced the second suspect that was arrested in connection to the Bangkok bombing last month had a formula that is used to create explosions.

According to CNN, the suspect was carrying a piece of paper with a chemical formula used to make explosions. National police spokesman Prawut Thavonsiri believes that the formula could have been volatile.

"These mix of chemicals you can easily obtain anywhere legally, but when you combine them, they become a chemical that is quick to catch fire and can be developed to become a detonator," he said.

"This formula can also be used to enlarge the radius of the bomb. It could be used for both of the bombings. But when the bomb detonates, this element (if used in the bomb) would disappear immediately because it's an amplifier."

Police identified the suspect as Yusufu Meerailee who was sharing an apartment with fellow suspect Adem Karadak. The two have been carrying falsified documents, and Meerailee was caught recently crossing the border of Cambodia. Karadak was arrested in the apartment.

Police are trying to determine if Meerailee was the man that was wearing a yellow shirt and a backpack caught on camera minutes before the attack.

The explosion took place at the famed Erawan shrine where thousands of people flock to pray everyday. The shrine is home to a golden statue of Phra Phrom, the Thai representation of Brahma, the Hindu god of creation. The Bangkok bombing killed 20 people and injured over 120 people on Aug.17. Among those who are confirmed deceased are a Chinese national and a Filipino national.

So far, police have a number of suspects in custody and believe that the bombing was carried out by a network of people. They do not believe it is a terrorist-based operation.

So far, no one has been charged with the bombing.
