ACP Abayomi Shogunle has responded to a question on if killing an armed robber under self-defense is a crime, and his response was ‘No’.
A twitter user had asked him if he was attacked by robbers in his home and he had weapons to defend himself, which he eventually used on them and caused them serious bodily harm. He wanted to know if that was a crime:

pls sir, if I am attacked by robbers and I have something like sword at home and I defend myself and get him injured seriously. Have i committed any crime sir?” He wrote
The Yomi Shogunle replied:
NO. It is called self-defence in law. Even if you kill the robber in stated circumstances your action is lawful; right to protect yourself, your family or your property from attack. I don’t think it is illegal if a house owner/occupant throws acid on robbers attacking the house.
