Pattani provincial police will investigate a complaint by the Internal Security Operations Command (Isoc) Region 4 Forward Command over a student call for a referendum on an independent "Patani state".
"We will set up a team of highly-experienced investigators to inspect witnesses and evidence before summoning those involved," Pol Maj Gen Archan Chansiri, chief of Pattani provincial police, said on Saturday.
Isoc's Region 4 Forward Command on Friday sent its soldiers to file the complaint with police.
