Mystery man in Bangkok bomb probe 'never said a word'

BANGKOK (Reuters) - The evidence seized by police investigating Thailand's deadliest bombing includes an apparently damning trove of explosives, fertiliser, and piles of fake passports, but the shabby-looking foreigner they arrested on Saturday remains a mystery.

There has been no word of his nationality, affiliation or whether the evidence seized in a shabby Bangkok apartment block amounts to a smoking gun for the attack on a crowded downtown shrine that killed 20 people two weeks ago.
