Thai court has issued a warrant for a fifth suspect involved in last week's Bangkok blasts, believed to be an "explosives specialist" who was providing training in bomb assembly and detonation to three suspects already detained by police.
The man, who has been named but not confirmed as Iranian national Javad Nikkahfard, 52, was captured on CCTV leaving the house at which a cache of explosives accidentally detonated on February 14.
He faces charges of manufacturing and illegally possessing explosives, and causing an explosion to physically harm others.
Last week, roof of a house allegedly rented by three Iranians blew off, sending the three men into the streets of Ekkamai. Two of them fled on foot but the third, Saied Moradi, 28, threw explosives at a passing taxi and again at police. In the melee he mistakenly detonated one of the bombs and blew off one of his legs. He remains in custody along with Mohammad Khazei, 42, who was detained by authorities while trying to board a flight the same day at Bangkok airport.
