90000 officers lost to insurgency in 4 years igp reveals
I think there may be some misinformation here.
The Inspector-General of Police (IGP) in Nigeria, Usman Baba Alkali, has not revealed that 90,000 officers were lost to insurgency in 4 years. In fact, the Nigerian Police Force has not reported such a significant loss of personnel to insurgency.
It's possible that you may have come across a misleading or outdated report. I'd like to clarify that the Nigerian Police Force has been working to combat insurgency and other security challenges in the country, and while there have been losses, they are not as significant as 90,000 officers in 4 years.
If you could provide more context or a credible source for this information, I'd be happy to help you verify it.
