Protesting against the death of six presumed to be the locals who went missing from Jiribam, a mob tried to barge into the personal residence of Chief Minister N Biren Singh on Saturday evening, setting off another big escalation between security forces and the protesters. The security forces had to resort to firing tear gas shells to disperse the assembled protesters. Earlier, protesters attacked the residences of at least three state ministers and six MLAs, prompting the government to impose prohibitory orders in five districts for an indefinite period and suspend internet services in parts of the state.
