Standing behind a podium topped with three bundles of banknotes, Somyot Pumpanmuang commended the detective work after the arrest of a foreign national whose name and nationality still remain a mystery.
"The accomplished work that led to the arrest is truly the work of the authorities and their investigative abilities... This was the work of the Thai authorities, there were no tip-offs." Somyot told a news conference.
Police have been criticised for a patchy investigation and have yet to say if the man arrested has provided any information or if his DNA samples, seized explosives, fake passports or telephone records connect him to the bombing at Bangkok's most famous shrine a fortnight ago.
