Interrogation is a method of extracting truthful information from a hostile or reluctant person by using an asymmetric interview method and specific questioning techniques.


Interrogation? Is that even legal?

Yes, interrogation is perfectly legal when conducted appropriately and by professional interrogators. Our interrogations do not involve physical or emotional torture, inhumane treatment, coercion, extortion, intimidation or threats of any kind. The subject (the person being interrogated) is under no obligation to participate in the interrogation, and is also free to terminate the process and leave at any time. Interrogation is simply an effective method of engaging, interviewing and questioning a person in order to extract truthful information and/or voluntary admissions from that person.

About Intertel's interrogation service

Our interrogators makes use of various creative questioning tactics based on their understanding of the subject's psychological and emotional state, the circumstances surrounding the matter under investigation (including external information regarding the subject or his/her knowledge of, or involvement in, the matter) - these tactics can include persuasion, deception, psychological or emotional manipulation.

We believe that the quality of the question determines the quality of the answer, and our interrogators are not only masters at asking questions that expose inconsistencies or extract sincere or factual answers, but they are adept at:

  • Rapport building
  • Active, attentive listening (and the ability to remember facts)
  • Detecting verbal and non-verbal signs of deception
  • The use of body language, proxemics and gestures
  • Predicting human behaviour (and the use of behaviour-provoking tactics)

When and where interrogations are conducted

Interrogations are usually conducted in the course of an investigation when,

  • 1 A person is suspected of involvement in the incident, act or activity under investigation
  • 2 He/she is believed to be withholding information that is pertinent to the investigation

An interrogation can take place at any venue - at your premises or ours - as long as the environment is controllable, and with as little external interference or distraction as possible.
