The government of Nepal has summoned the British ambassador in Katmandu to protest over the arrest of a Nepali army officer in the UK over allegations of torture.
It was reportedly committed during the Himalayan's nation's decade-long Maoist insurgency.
Deputy Prime Minister Narayankaji Shrestha told reporters that the government has demanded the immediate release of Col Kumar Lama. Nepal has also instructed its embassy in London to submit a protest note to the British government.
The Metropolitan Police arrested the 46-year-old yesterday in St. Leonards-on-Sea, East Sussex.
Nepal officials said Col Lama is serving as a military observer under the UN Mission in Southern Sudan and was on a holiday in London.
Scotland Yard said the arrest did not take place at the request of Nepali authorities.
The details of the alleged offence have not been made clear. British authorities claim "universal jurisdiction" over serious offences such as war crimes, torture, and hostage taking.
Thousands died and thousands more were injured or tortured during Nepal's civil war, a decade-long conflict which ended in 2006.
