Many Nigerians travelling as tourists have been arriving in Nepal and getting involved in illegal activities, including narcotics. The police say several of them have set up the drug operations in rented houses. Last year, police arrested 11 Nigerians with drugs, including four women, after raiding a rented house in Bisalnagar. Dozens of Nigerians have also been staying in rented flats in Bhotahiti, Thamel and in Shankamul. Police say they are now more vigilant about Nigerians living in residential areas but they are hampered because Nepalis themselves are helping to arrange their stays. Dealing in drugs is just one of their alleged illegal activities. Recently, four Nigerians swindled Rs 25,000 from Hotel La Meridian in Gokarna. In another incident, a group of Nigerians tried to cheat a popular restaurant by paying with fake dollar bills. Every night, Nigerians are seen in large numbers in Thamel's inner areas and they frequent Funky Buddha, Tom and Jerry, Full Moon, Sam's, Fire Club, JBar and dozens of other pubs. Around 30 Nigerians are said to be entering Nepal monthly and their numbers have already reached 500 in Kathmandu alone. Immigration officials now say they will take action against Nigerian tourists who are trying to stay illegally in the country and they have already sent letters to hotel associations, municipalities, ward offices and trekking agencies to be on the lookout for suspicious Nigerian tourists. The Home Ministry has also said that it will take tough measures against the growing illegal activities of the Nigerians.
