The 18 kidnapped people, according to an eyewitness, were travelling in three commercial vehicles when they ran into a blockade by the bandits at Kundu town, a few kilometres from Zungeru town.
Kundu was the town, where 42 passengers travelling in the Niger State Transport Authority (NSTA) vehicle were kidnapped over three weeks ago.
Government later secured the release of the commuters eight days after their abduction.
The passengers in the three vehicles were abducted and taken to an unknown destination, while the vehicles were left by the road side.
The bandits also ransacked the houses of the villagers, stealing foodstuff and other valuable items. The police were yet to react to the two incidents.
