There are travel advisories from pretty much all English speaking countries that recommend avoiding Nigeria if possible.

Violent crime – such as armed robbery, assault, carjacking, kidnapping, hostage taking, banditry, and rape – is common throughout the country. Kidnappings for ransom occur frequently, often targeting dual national citizens who have returned to Nigeria for a visit, as well as U.S. citizens with perceived wealth. Kidnapping gangs have also stopped victims on interstate roads.https://www.smartraveller.gov.au/destinations/afri...Internet romance, friendship and employment scams often start in Nigeria. If you travel to Nigeria as a scam victim, you may expose yourself to the threat of physical harm or theft. Be wary of online contact from people you don't know. Don't send money until you've checked who you're sending it to.https://www.gov.uk/foreign-travel-advice/nigeria/s...British nationals are increasingly being targeted by scam artists operating in West Africa. The scams come in many forms including romance and friendship, business ventures and work or employment opportunities. Scams can pose great financial risk to victims. You should be very cautious about any requests for funds, a job offer, a business venture or a face to face meeting from someone you have been in correspondence with over the internet who lives in West Africa.In short, there is a high likelihood that your friend is being scammed, and she may be robbed, kidnapped, ransomed, raped, trafficked, murdered, or some combination of the above.
