Nepal's high court has ordered the release from prison of Charles Sobhraj, the notorious French serial killer who also inspired the award-nominated TV series Snake.
The decision according to the Court came because of his age and health.
Sobhraj, 78, had been serving a life sentence in a prison in the Kathmandu suburb of Bhaktapur for killing two tourists in 1975, but many of his alleged murders remain unsolved. Sobhraj suffers from a heart disease and needs an operation.
Born in Saigon, a French-administered enclave, Sobhraj was first jailed in Paris in 1963 for theft, but went on to be accused of committing crimes in a list of countries: France, Greece, Turkey, Iran, Afghanistan, Pakistan, Nepal, India, Thailand and Malaysia. He also escaped from prison in several countries and his tendency to evade the authorities earned him the nickname "The Snake".

Before he was sentenced in Kathmandu, Sobhraj had already spent twenty years in prison in India for poisoning French tourists on a bus.
During this time, he managed to escape from prison for a while by drugging the prison guards. He later claimed the escape was a ploy to extend his sentence and avoid extradition to Thailand, where he was wanted for five more murders.
According to his biographers, Sobhraj eventually confessed to at least 12 murders between 1972 and 1976 and left others pending before retracting his confessions ahead of other court cases. His true death toll is unknown.
The 2021 BBC/Netflix drama The Snake is based on the story of Sobhraj's alleged murders. It tells how for years he evaded the law across Asia, allegedly drugging, robbing and murdering backpackers along the so-called "hippie trail".
