Thida added that she wanted police to bring those responsible for arson and for killing people during the political mayhem to justice.
In response to the petition, Metropolitan Police deputy commissioner Maj-General Anuchai Lekbamrung said police had cooperated with the Department of Special Investigation in solving the arson case, which led to an acquittal verdict. Should the red shirts have fresh evidence, police would be happy to pursue the new lead, he said.
Metropolitan Police commissioner Lt-General Kamronwit Thoopkrajang said he would appoint an investigative panel to re-examine the facts related to the arson case.
Separately, the red shirts will hold a rally on April 10 at Rajdamnoen Avenue to mark the months-long protest in 2010. The April 10 rally is scheduled to run from 1pm to midnight and motorists are advised to avoid the area.
