A Thai man who has been identified as the suspect behind a deadly bomb attack in Phuket, Thailand, last week is reportedly on the run in Malaysia.

Thai newspaper The Nation reported that an arrest warrant was issued after DNA collected at the bombing site matched that of Ahama Lengha in relation to a previous case in 2008.

Officials, however, refused to say how authorities had collected a sample of his DNA from 2008.

An arrest warrant was also issued in 2008 for Ahama over his suspected involvement in acts of violence in the south of Thailand. He had however refused to comply with several summonses to report to authorities.

Ahama reportedly works at a fertiliser factory in Malaysia, located 15 kilometres from his house. It was also reported that he returns home every weekend.

The suspect had purportedly arranged to turn himself in under a plea-bargain deal over the 2008 case a few days before the bomb attack last week, but disappeared after the new arrest warrant was issued.

The bombing attacks last week saw four people killed and dozens wounded.

No group has yet claimed responsibility for the bombings, which came days after Thais voted to accept a military-backed constitution.

Police and the government ruled out any link to foreign militants within hours of the attacks and insisted the perpetrators were home-grown.

Suspicion has fallen on domestic political groups including supporters of ousted former prime minister Thaksin Shinawatra, who was forced from office in 2006.

While Thaksin’s supporters have not been blamed outright, police said last week the attacks were carried out simultaneously by one group on the orders of one person, but gave no further details.

Lawyers for Thaksin have been instructed to file complaints against those accusing him of orchestrating the blasts.

Thai deputy national police spokesperson Kissana Phatanacharoen said police were working with Malaysia to track down other suspects.
