Among those summoned are Sermsuk Kasitipradit, the political editor of public television channel TPBS, and a local pro-government protest leader.
The postings mentioned a possibility of a military coup and urged the public to hoard food and water.
“Those who ‘liked’ and ‘shared’ the posts will also face charges, so we would like to ask the public to contemplate very carefully about the way they use social media,” Pisit added.
More than 1,000 anti-government protesters kicked off a rally in Bangkok on Sunday as lawmakers were scheduled to deliberate on the controversial bill on Wednesday.
Last week, the government invoked the Internal Security Act in three Bangkok districts, citing the possibility of protest violence. The act, in effect from Aug. 1 – 10, authorizes officials to seal off roads, take action against security threats, impose curfews and ban the use of electronic devices in designated areas. Peaceful and unarmed rallies are allowed under the law.
Opponents of Prime Minister Yingluck Shinawatra’s government feared the bill, which would grant amnesty to people arrested for political activities since the 2006 military coup, could pave the way for the return of her brother Thaksin.
Thaksin was ousted in the 2006 coup and has been living in self-imposed exile.
The government’s special peace-keeping command under the Internal Security Act warned on Sunday against sharing any information that could lead to havoc in the nation.
Army chief Gen. Prayuth Chan-ocha on Monday denied the coup rumors and urged the public to be careful in distinguishing truth from rumors.
“Do not spread the rumors. Rumors are rumors. I want every group, every side, everyone, no matter which side you’re on, to be sensible … and be able to see what is true and what isn’t,” Prayuth told reporters.
