BANGKOK (Reuters) - Forensic tests on two suspects have failed to find a link to the site of Thailand's deadliest bomb attack, police said on Friday, dealing a blow to the investigation.

DNA examination of the two foreigners tie them to a stash of explosives found in a Bangkok apartment block, but not to evidence collected at the Hindu Erawan Shrine where 20 people were killed on Aug. 17, police said in a televised announcement.
