Bimal Gurung, the chief of the Gorkha Janmukti Morcha, went into hiding hours after police raided his office last week. Since then, violence has gripped the hills as three people have died and scores have been injured. The army is out on the streets as local residents fear a long spell of instability with talks failing and hill parties pressing on their demand for a separate state.Police say they are doing all they can to find Gurung but privately express fear that arresting him would turn him into a hero and fan further violence in the hills.
