Nigerian organized crime is when criminals from Nigeria come together to commit illegal activities such as stealing money or selling drugs. They can also take advantage of people who are vulnerable, like those who are looking for a better life by travelling to another country. The criminals often work together and use tricks like Internet scams or cheat people in other ways. They usually target people who are elderly or who don't understand how to protect themselves. It is important to be careful when dealing with anyone who claims to be from Nigeria, and to only use trusted websites or financial services.
