Rector tetfund spends n3 4bn on infrastructure at bida poly

I think there may be a slight mistake in your statement. The rector of TETFund (Tertiary Education Trust Fund) is not responsible for spending N3.4 billion on infrastructure at Bida Poly. TETFund is a federal government agency established to provide funding to public universities in Nigeria to improve their infrastructure and academic programs.

Bida Poly, on the other hand, is a polytechnic located in Bida, Niger State, Nigeria. The rector of Bida Poly would be responsible for managing the institution's budget and making decisions on how to allocate funds for various projects, including infrastructure development.

If you could provide more context or clarify what you mean by "rector tetfund spends n3 4bn on infrastructure at bida poly", I'll be happy to help you understand the situation better.
