Thailand's police on Friday have prepared to seek court approval for arrest warrants for seven people in connection with the bomb attack at the major coalition Bhumjaithai Party (BJT) headquarters in north Bangkok on Tuesday, the Thai News Agency (TNA) reported. With the arrest warrants the seven will be charged of planting the blast at the major coalition Bhumjaithai Party headquarters. One of them is a Buddhist monk, Metropolitan Police deputy chief Pol Maj-General Amnuay Nimmano said, the Bangkok Post's website reported. In a related development, Deputy Prime Minister in charge of security affairs Suthep Thaugsuban said it has not been concluded if the bomb attack is linked with an anti-government-underground movement. The bomb attack occured despite of the ongoing enforcement of the state of emergency as the bomb attack is seen affecting the government's decision on whether the law should be lifted or not. Though the anti-government protests ended on May 19, the government has still maintained its enforcement of the state of emergency in order to ensure security for the public. The state of emergency has been imposed from April 7, 2010, in 24 provinces of Thailand's 76 provinces, empowering police and army to control the then anti- government protests. The death toll from a series of violent clashes between the ' red-shirt' protestors and troops during March 12 to May 19 stood at 88 as some 1,885 others were wounded.
