About 100 red-shirts rallied in front of the head office of <i>Thai Rath</i> newspaper on Vibhavadi Rangsit road on Tuesday afternoon, demanding action against cartoonist Somchai Katanyutanan, better known by his pen name Chai Ratchawat.
The red-shirts, led by Chatchawal Kritchanasut and Jutipong Poommoon, demanded to know what action the newspaper had taken against one of its most popular cartoonists.
On Friday, a lawyer representing Prime Minister Yingluck Shinawatra lodged a police complaint accusing Somchai of defaming the prime minister in his comments posted on his Facebook page.
Prakit Limsakul, adviser to the head of the Thai Rath editorial department, received a letter containing demands from the protesters.
He told them the matter was regarded as personal, but agreed to take their demands for consideration.
