Kathmandu Valley is still simmering with protests by students after two youngsters were lynched this week when locals mistook them as kidnappers.

There is growing involvement of Indians and border villages in India's Uttar Pradesh and Bihar are increasingly being used to keep the victims in captivity till their families pay ransom.

Last month, a six-year-old boy who was spirited away from his school in remote Kailali district, was rescued from Lakhipur village across the border to Uttar Pradesh.

A 42-year-old teacher from India's Darjeeling town is in a Nepal jail for allegedly kidnapping an 18-year-old student, murdering her and then cutting up her body into pieces so that she would not be recognised.
