Bangkok, A group of 15 suspects detained by the Thai military investigating last week's deadly tourist resort attacks was not involved in the blasts, police said today, adding to confusion surrounding the case.
The junta said yesterday the detainees had been held during their investigation into the bombing spree, which hit tourist towns in the south, killing four and wounding dozens, including Europeans.
But today police said the group - many of whom are elderly - had in fact set up an illegal political party to overthrow the regime.
The bombs attacks were highly unusual in a country where foreigners and tourist towns are rarely caught up in the country's frequent bouts of political violence.
Investigators have been under pressure to make quick arrests.
The group appeared at a Bangkok police station today escorted by soldiers - the first time they have been seen in public - to hear the charges against them.
Two are women and many of the men are in their 60s and 70s.
Thai media have run multiple reports quoting anonymous investigators as saying the group helped coordinate the recent attacks.
But Major General Chayaphol Chatchaidej, a senior official at the Office of Police Strategy who was at the police station to receive the suspects, told reporters they were not involved.
"There is no evidence linking them to the bomb attacks in the seven southern provinces based on our investigation, although some of them are involved with lese majeste (royal defamation) and arms trafficking," he said.
Instead he described them as a splinter faction of the anti-junta Red Shirt movement loyal to ousted Thai premier Thaksin Shinawatra, who was toppled by the military in 2006.
He said the network called itself the Revolutionary Front of Democracy party - a previously unheard of group.
A police statement handed to reporters listing the suspects' names and ages said the group aimed to "accumulate arms... and overthrow the government" but made no reference to last week's bomb attacks.
The statement said they currently face one charge of breaching the junta's ban on political gatherings and another of belonging to an unlawful secret society.
That means no arrests or charges have yet been announced for people directly responsible for the blasts.
Thai police and military have a history of rivalry but since the 2014 coup the military have spearheaded national security investigations.
