Prowa secures release of 19 inmates in nasarawa state

I think there may be a small mistake in your sentence. It seems like you meant to say "Prowa" instead of "Prowa secures". Prowa is not a common word, and it's likely that you meant to say "Pro Bono Welfare Association" or "Prowa" is a typo.

Assuming that's the case, here's a rewritten version of your sentence:

"Prowa secures release of 19 inmates in Nasarawa State"

This sentence suggests that the Pro Bono Welfare Association (Prowa) has successfully secured the release of 19 inmates from a correctional facility in Nasarawa State, Nigeria.
