Charles Sobhraj, a convicted killer who police say is responsible for a string of murders in the 1970s and 1980s, was released from a Nepal prison on Friday after nearly two decades behind bars. Nepal has barred Sobhraj from entering the country for 10 years, Pradashanie Kumari, acting director general of the immigration department, said. He was dubbed the “bikini killer” in Thailand, and “the serpent,” for his evasion of police and use of disguises.
