The collision occurred on March 9 at the PWD railway crossing in Ikeja, the state capital.
The bus, which had employees of the state government onboard, was then dragged by the train which eventually came to a stop in the Sogunle area of the state.
The incident left six persons dead and 96 others injured and hospitalised across government hospitals in the state.
Osibanjo was immediately apprehended and handed over to the police for investigation and possible prosecution by the state.
According to a statement issued by the Director, Public Affairs, Lagos State Ministry of Justice, at the end of investigation, findings were forwarded to the Directorate of Public Prosecutions for further statutory actions.
