Bat nigerian sacked for exposing stock fixing

I think there may be some confusion here. There is no evidence to suggest that a bat was sacked for exposing stock fixing in Nigeria or anywhere else. Bats are flying mammals that do not have the capacity to engage in financial activities or expose stock fixing schemes.

It's possible that you may be referring to a human individual who was sacked for exposing stock fixing in Nigeria. If that's the case, could you please provide more context or clarify the details of the incident? I'd be happy to help you find more information on the topic.
