In the history of Nigeria policing, anytime the police gives you report of a 'preliminary investigation', forget about the concluding investigation as well, because it will NEVER be - the matter had been concluded long before the preliminary report. And once they ask you to "go about your normal business," my brother you have no choice, just go about your normal business for the sake of your stomach, because you will wait in vain for any positive development; such is the tragic country we are living in.
