:: The police have power to elicit information, unravel facts and evidence prior to institution of the case pursuant to their duties in Section 4 and 23 PA[1]. They may ask questions, take measurements, empirical analysis, medical examination, etc.

Where the offence is a minor one and suspect does not deny the accuracy of the report, he can be questioned through telephone, written representation or through agent.


Investigations should be conducted within the ambit of the law.

  • The person being invited for interview should be told of the alleged offence occasioning the interview and in what status he is being interviewed/investigated. i.e. whether as witness, accused, victim, etc.
  • Dignity and freedom from unnecessary restraint of the interviewee/suspect. No torture, coercion, influence or force should be used-34 CFRN
  • Right to remain silent until he consults with a Legal Practitioner of his choice who is also entitled to be present at the interview Section 35(2) of the 1999 Constitution. Where he cannot afford one; an officer of legal aid council, civil society or justice of peace or other person of his choice. Section 3 ACJL.
  • Right to an interpreter at no cost if he does not understand English-Section 36(6) CFRN.
  • Right to be presumed and treated as innocent until proven guiltySection 36(5).
  • The offence for which he is arrested must be known to law-Section 36(12) CFRN Aoko v Fagbemi.
  • Right not to be re-arrested for offence he has already been convicted or acquitted for-Section 36(9)
  • Right to be informed in Writing of the facts and grounds for arrest within 24 hours and in the language he understands-Section 35(3) CFRN[2].

  • Right not to be arrested in place of a suspect-Section 4 ACJL, 7 ACJA.

Interview should be in police station or other authorized place except likely harm or interference with interviewee, interviewer, evidence, people or property would be occasioned.

: JUDGES RULES: To set certain standards, judges rules (from common law) have been formulated. They mandate that statements are voluntarily made[4] by suspects for example; that suspect be cautioned (in his language) on the possible implications of answers he gives to questions he is about to be asked, interpreter entitlement and calling. (see also 29 EA 2011 on voluntariness of confessions).

Note that Judges Rules are for Administrative Convenience rather than binding-Usman v The State. It just affects the weight the court would attach to the statement.


Where the identity of the suspect is in issue Ani v The State, Agboola v The State. Usually where the incident lasted a short while and the victim did not know the accused. The Suspect(s) must be assembled with about 8 (or 12 for more than one suspect) persons of similar physiognomy. Victim should not be allowed to see (or get the accused’s picture). Identification parade would not be necessary where the suspect is well known, arrested at the scene of the crime or well seen committing the offence. The identifier should not be assisted-R v Chapman.

:: LEGAL AID SCHEME: For indigent accused Earning below #18,000 and for matters mentioned in the Legal Aid Act. See Section 8 Legal Aid Act he is to complete Form LAC 2, be interviewed and thereafter assigned with a counsel.


:: HOW EXHIBITS ARE KEPT AT THE POLICE STATION. Things seized be itemised in a list to be signed by suspect, searcher and witnesses-149 ACJA. Then be registered and kept by exhibit keeper in exhibit room. The exhibit keeper then tenders in evidence.
