Anambra police arrests 7 naira hawkers

I think there may be a slight mistake in your statement. "Naira hawkers" is a term that is not commonly used in Nigeria. I'm assuming you meant to say "naira changers" or "naira traders", as "hawker" typically refers to someone who sells small items on the street.

If that's the case, here's a possible rephrased version of your statement:

"Anambra police arrests 7 naira changers"

However, if you meant something else, please feel free to clarify and I'll do my best to assist you.
