Bangkok: Thailand`s junta today freed leaders of the "Red Shirt" movement allied to the ousted government, as social media users reacted with alarm to rumours of a "block" of Facebook.
Since seizing power last week the military has summoned more than 250 people, curtailed liberties under martial law and imposed a nightly curfew as part of a series of measures that have sparked dismay among rights groups.
Analysts say the move to detain political figures from across the kingdom`s bitter divide is aimed at quelling potential opposition to the May 22 coup.
After an outcry on the Internet, the army interrupted national television to deny it had blocked Facebook after the site briefly went down and caused panic online.
"Surely that would be suicide. Whole country would protest," one user wrote on Twitter of the rumours the site was under siege in the kingdom.
Some users were unconvinced with the junta`s denial, speculating that it could have been a trial run for a possible blackout in the future, or a warning shot to social media users not to criticise the coup.
Social media platforms such as Twitter and Facebook are hugely popular in the country, and have been used by anti-coup protesters to organise small protests against the military regime.
Despite warnings by the army of a widening crackdown on dissent, protesters have been gathering in Bangkok in small but vehement rallies against the military takeover, while rival pro-coup rallies have also sprung up.
But in a possible sign that the army is more confident about its grip on power, key members of the Red Shirts protest group were released Wednesday after nearly a week in detention.
The movement`s chairman Jatuporn Prompan said they were "treated well".
"What we have been most concerned about is that the losses of life in 2010 should not happen again in 2014 -- we should learn the lessons," he said, referring to a bloody military crackdown on their rallies against a previous government that left dozens dead.
The army has said people who have been detained and released since the coup must sign a document promising to cease political activity.
