Thai police said on Monday that they were holding a third Iranian for questioning in connection with an alleged plot to kill Israeli diplomats in Bangkok.
The man, who has denied any links to a string of botched blasts in the Thai capital on February 14, was charged with overstaying his visa, said the police.
According to Thai media, mobile telephone call logs showed he had been in regular contact with two Iranians now in custody, one of whom was badly hurt as he hurled a bomb at police while fleeing. An Iranian couple were also taken in for questioning but were later released because police found nothing to indicate they were involved.
