The passerby died in multiple accidents that involved three vehicles at the toll gate on Lagos-Abeokuta Expressway.
The disaster occurred during a heavy overnight downpour in which many people were injured in Kankara, Nasarawa and Matsiga communities.
During the heavy rain, several houses collapsed and the roofs of others were blown away by the rainstorm.
The police said they apprehended a staff of the farmer, in connivance with his friend, on their way to Kano with stolen 36 rams and six goats.
The suspect said he, his eight wives and 50 children have been living off the illicit trade since he retired from the military in 1982.
The Katsina State Emergency Management Agency (SEMA) says over 1,500 houses were affected by a downpour experienced on Monday.
