Bangkok: An Iranian national was on Monday formally charged by the Thai Police for his alleged role in last week's triple blasts that rocked central Bangkok in what is seen as a botched attempt to target Israeli diplomats.
Mohammad Hazaei, who was arrested at Suvarnabhumi International Airport last Tuesday while trying to flee to Malaysia, was questioned at the Metropolitan Police Bureau.
Deputy Metropolitan Police Chief Pansiri Prapawat, who is heading the investigation, formally notified him of the joint charges, with the other three suspects.
The charges include assembling explosive devices, possessing explosive devices without a permit, and causing an explosion injuring other persons and property.
Deputy National Police Chief Jarumporn Suramanee said the DNA test showed links between Hazaei and evidence such as clothes, hats and shoes collected from the rented house where the first explosion took place.
He said the DNA test to determine connections with another suspect Saeid Moradi, who lost both legs when his own explosive device rebounded, has not yet been conducted.
Meanwhile, the Criminal Court has issued arrest warrants for the fifth Iranian suspect in connection with the February 14 Bangkok bomb incidents.
The fifth suspect is a Middle Eastern man who may have been involved in the blasts.
CCTV camera images showed him walking from the rented house where the first explosion took place.
He was suspected of training other suspects to assemble bombs.

Police added that it could not be confirmed if the suspect in was N Javad as was previously reported.

The police also declined to give more details about the confiscation of a motorcycle near the explosion site.
They are probing if the bike could have been intended for use in a bomb plot.
A third Iranian identified as Masoud Sedaghatzadeh was arrested last Wednesday by Malaysian authorities in Kuala Lumpur.
The Thai authorities are working to conclude and translate related documents to be submitted to Malaysia for the suspect's extradition to Thailand.
The fourth suspect is an Iranian national identified as Leila Rohani, a woman who reportedly rented the house for the group and returned to Tehran several days before the blasts.
Meanwhile, a Muslim academic on Sunday warned the Thai government that the country could be drawn into an international conflict.
Sulaiman Husainee, director of Al Mahdi Institute, said pressure would be mounting after Thailand recognised the right of Palestinians to an independent state.
"I'd like to urge security authorities not to dance to the tunes of the United States and Israel," he was quoted by the local media as saying.
The February 14 explosions were linked to recent blasts in India and Georgia.
The Iranian diplomatic mission here denied Iran was involved.
