Malaysian officials believe they may have identified the two men responsible for the Bangkok bombing that occurred last month.

The International Business Times reports Malaysian officials released photographs of two detainees. One of the detainees is believed to be the "yellow shirt" man, who was caught on tape leaving a black backpack at the scene minutes before the explosion occurred. The other detainee was wearing a "blue shirt," and was the one who threw the other bombing device into the Chao Phraya River, where it exploded.

Thai security agencies will look back at the security tapes in order to determine if the men are the ones captured in the CCTV security footage. Uniformed cops and plainclothes police officers raided several rented rooms and apartments belonging to the Bangkok bombing suspects this weekend.

Yusufu Meerailee, who was arrested earlier this month in connection to the bombing, will also be shown the photographs. Meerailee admitted to police he met the bombing suspect and gave him the backpack with the explosives used in the attack. If he confirms one of the men in the photographs to be the bomber, Thai police would ask for extradition from Malaysia in order to prosecute the suspect in Thailand.

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, a number of suspects have been arrested, but no one has been charged with any crime. Officials believe that the bombing was carried out by a network of people, and they do not believe it is a terrorist-based operation.
