The Sector Commander, Federal Road Safety Corps in Ogun, Ahmed Umar, confirmed the incident to newsmen in Abeokuta.
Umar said that the accident occurred around Conoil in Araromi before Sagamu Interchange on the expressway.

According to him, the vehicles involved in the accident are: a Mack truck marked AKL 198 ZT; an Iveco truck with no registration number; a Mazda bus marked FFE 361 XB, an unmarked Howo truck and the Mack tanker.
He attributed the cause of the accident to speeding by the driver of the Iveco truck.
“Driver of the Iveco truck, who was travelling on top speed lost control and rammed into the tanker, which resulted to fire outbreak due to leakage,”
He added that the Mazda bus was engulfed by the fire, saying that all those that died were in the bus.
