You are walking down Allen Avenue on a Tuesday evening when two officers pull up beside you and ask you to stop. They have not seen you commit a crime. You have not done anything — at least, not that you know of. But they say they had “reasonable suspicion.”
Is that legal? Can they search you? Do you have to answer their questions?
The answer to all three is: it depends. And the line between what is permitted and what is a violation of your rights is one that most Nigerians — and many police officers — do not fully understand.
What the law actually says
Under the Nigerian Police Act 2020, a police officer has the authority to stop, detain, and question any person they reasonably suspect of having committed, or being about to commit, a criminal offence. The key word is “reasonably.” The suspicion cannot be arbitrary. It must be based on observable facts or circumstances — your behaviour, your location, the time of day, information received — not simply on how you look or who you are.
In practice, however, reasonable suspicion has become one of the most abused provisions in Nigerian law enforcement. Officers invoke it to justify stops that are rooted in profiling, harassment, or the expectation of collecting a bribe.
What “reasonable” is supposed to mean
Reasonable suspicion sits below the threshold of probable cause. It does not require evidence strong enough to secure an arrest or a conviction. But it is not nothing either. Courts have, in various rulings, held that reasonable suspicion must be:
- Specific: the officer must be able to point to particular facts, not a general feeling
- Articulable: the officer must be able to explain those facts in words
- Objective: a neutral third party — a judge, for instance — must be able to agree that those facts could justify suspicion
What this means in plain terms is that “he looked suspicious” is not enough. “He was standing outside a closed shop at 2am, holding a torch, and ran when he saw the patrol vehicle” is closer to what the law envisions.
What you can and cannot be asked to do
If an officer stops you on the grounds of reasonable suspicion, you are required to identify yourself. In Nigeria, there is no single mandatory national ID, but you are expected to cooperate with identification requests. Refusing outright can escalate a situation in ways that are unlikely to benefit you.
You are not, however, required to consent to a search of your person or your belongings simply because you have been stopped. An officer needs either your consent, a search warrant, or grounds that go beyond reasonable suspicion to conduct a search. Saying “I do not consent to this search” clearly and calmly is within your rights.
You are also not required to answer substantive questions about where you are going, where you have been, or what you are doing. You can say: “I am happy to identify myself, but I would prefer not to answer further questions without knowing why I have been stopped.”
The evidence problem
Here is where Nigerian law diverges sharply from what many people assume, particularly those familiar with American legal dramas. In the United States, evidence obtained through an unlawful stop or search can be thrown out of court under what is known as the exclusionary rule.
Nigeria does not have an equivalent rule in the same form. Under the Evidence Act 2011, a court has discretion to admit evidence even if it was obtained illegally, provided its probative value — its usefulness in establishing the truth — outweighs the manner in which it was obtained. In practice, this means that even if your rights were violated during a stop, anything found on you could still be used against you in court.
This is not a technicality. It is a structural feature of the Nigerian legal system that has serious implications for how citizens interact with law enforcement. Knowing your rights is important. Knowing the limits of those rights is equally so.
What to do if you believe your rights have been violated
Document everything as soon as it is safe to do so. Write down the time, location, names or badge numbers of the officers if you can obtain them, and exactly what was said and done. If you were searched without consent and something was taken, note what it was.
You can file a complaint with the Police Service Commission, report to the National Human Rights Commission, or consult a lawyer about pursuing a civil claim. None of these paths are easy or fast. But they exist.
The law is only useful if you know what it says.
