Kidnapping for ransom is rife in northwest Nigeria where armed gangs, often referred to locally as bandits, have targeted schools and villages, making it unsafe to travel by road or to farm in some areas.
Kaduna police spokesperson Mansur Hassan said the police are investigating the incident, which occurred late Tuesday in Chikum local government area of the state.
Mohammed Danjuma, a resident who was spared, said about 16 people were taken but eight managed to get away.
"As they were busy trying to break into my apartment, one of the vigilantes in the community fired a shot into the air, which made the bandits uncomfortable and left," he said.
Malam Suleiman, another resident who was kidnapped, managed to escape while being led into the bushes. His teenage sons were taken by the bandits.
Attacks in northern Nigeria are part of widespread insecurity in the country that include a 14-year Islamist insurgency in the northeast and deadly clashes between farmers and herders in the central region.
