The CPM-led LDF has called a State-wide hartal on March 11 to press its demand for a judicial probe into the violence and police firing at Muthanga which claimed the lives of a policeman and an Adivasi. Opposition Leader V.S.Achuthanandan and other legislature party leaders told mediapersons here on Thursday that the LDF would meet again on March 6 to chalk out its course of action to press the demand for a judicial inquiry into the Muthanga incident.
