The 2014 kidnap of 276 Chibok schoolgirls brought global attention to raids on schools in Nigeria. Now criminals are making money with copycat crimes. Nearly 300 girls were kidnapped from a boarding school last week, then released four days later after a ransom was paid. One girl said, ‘Most of us got injured, and we could not carry on walking. They said they would shoot anybody who did not continue walking. We walked across a river and they let us sleep under shrubs in a forest.’ Their release was secured through negotiations between government officials and the abductors. Kidnapping for ransom is a widespread criminal enterprise. Both rich and poor are seized by gunmen on almost a daily basis. Security personnel have also been held. The aim is to secure someone's release by raising funds from friends and relatives - or even selling their assets.
