Cbn declares omo poison for banks

I think there may be some confusion here.

CBN stands for Central Bank of Nigeria, which is the country's central bank. Omo is a type of treasury bill issued by the CBN to raise funds for the government.

"Omo" is not a person, and it's not possible for the CBN to declare someone named "Omo Poison" for banks.

It's possible that you may have come across a misleading or satirical article or social media post. If you could provide more context or clarify what you're referring to, I'd be happy to help you understand the situation better.
