New Delhi, Sept. 14 -- Nepal remains on high alert as army personnel continue to patrol the streets after criminal elements reportedly gained access to weapons looted from police armouries and several inmates escaped from jails across multiple districts, officials familiar with the development said. Nepal's first woman chief justice, Sushila Karki, took oath on Friday as the Himalayan nation's interim prime minister to lead a six-month transition to elections, two days after violent anti-corruption protests ousted the government. The neighbouring country of 30 million people was plunged into chaos earlier this week after security forces tried to crush rallies by young anti-corruption protesters. At least 51 people were killed in the worst violence since the end of the civil war and the abolition of the monarchy in 2008. The Nepal Police are yet to officially comment on the exact number of prisoners who escaped, but people aware of the matter said it is anywhere between 7,000-12,000 prisoners. "The main worry is not the protesters but those with arms and ammunition stolen from police stations. Another worry is the prisoners who fled from the jails. While the protesters got one of their demands met, the criminals may not be bothered about this development. They will try to use the weapons to loot people, if they are on the streets at this hour. Civilians should not move around at night until all weapons are recovered or the hardcore prisoners are back in jail," an army officer, posted on a road near the charred Nepali Parliament building in Bageshwor, said on Friday night....
