The Centre for Maintaining Peace and Order (CMPO) on Friday issued a summon for those who blew whistles at former wilfe of Thaksin Shinawatra.
CMPO's member Tarit Pengdit said if they fail to report themselves, he will seek arrest warrant against them.
Earlier a pipe bomb was thrown into house of a rally leader who blew at whistle at the former wife of fugitive expremier Thaksin Shinawatra in Klong Toey district early this morning. The bomb however was a dud and failed to explode.
Police were alerted to the attack at 2.20a when explosives in a blue PVC pipe were found at the house of Nataphol and Taya Teepsuwan in Sukhumvit Soi 18.
Security guards said a motorcycle has been spotted near the house at 12.30am but they could not see face of the driver or the vehicle’s registration plates.
The guards added that the driver then drove the vehicle to the front of the gate and threw the explosive. Police believe the attacker intended to intimidate rather than cause injury.
The couple was among a group of antigovernment protesters who blew the whistles at Khunying Pojaman Na Pombejra while she was shopping at The Emporium shopping complex on February 26. Videos of the incident went viral on YouTube, with some of them blocked minutes after they were posted.
On Friday, Nataphol wrote about the incident on his Facebook page, saying “as expected, a pipe bomb was thrown into my house. Luckily, it was a dud. The attack is likely to be resulted of the whistle blowing. Despite this, we will not back off. We are different from you and your boss and there will be no violence from our side for sure,” he said.
