Interrogation is the extraction of information one by another used by both CTU agents and terrorists. There are different types of interrogation, such as psychological interrogation, pharmaceutical interrogation, and torture. The different types can be used in conjunction, as well as separately.
Torture is a form of interrogation that implements pain in order to forcibly extract information from a source, such as a terrorist or suspected mole. Many people have been tortured or interrogated in order to release vital information.
Day 1 Edit
- Ted Cofell: was threatened by Jack to have a towel thrust down his throat if he didn't cooperate. Cofell claimed not to know anything, but later lunged at Jack with a HALO knife. Bauer broke his wrist and punched him in the heart. Due to his heart condition, he died.
Day 2 Edit
- Jason Park: Park being tortured is the opening scene of Day 2. He is electrocuted in an intricate machine that monitors his blood/saline levels while delivering painful electric shocks.

Bauer threatened to kill his family if he did not confess. Jack faked the death of Asad Ali, and Syed broke when Jack made it appear that his other son would be killed next.
- Jack Bauer: Jack was tortured by Ronnie Stark and his heart accidentally stopped. He then developed a heart condition and Raymond O'Hara killed Stark.
- Marie Warner: Marie was eventually caught by Jack and her sister Kate Warner and was interrogated by Jack Bauer. She was shot in the arm and the bullet was not removed, causing intense pain.

- Michael Amador: In order to force him to surrender the location of the Cordilla virus vials he sold to Stephen Saunders, Jack and Chase tortured Amador, Chase slicing his hand in the process.

- Paul Raines: After CTU discovered Paul's name on the lease of the building where the terrorist attacks had been planned, Jack tortured him by electrocuting him with wires from a lamp, despite Paul's (truthful) insistence of innocence, and Audrey's pleas for mercy on her husband. Later, Paul was tortured by McLennen-Forster security guards in order to find the location of documents Paul hid which incriminated the company in the day's terrorist attacks, but Jack saved Paul by killing all three guards.
- Joe Prado: A court order from one Judge Norton prevented CTU from interrogating Joe Prado, one of Habib Marwan's associates.

Though maybe not the only technique employed, water-boarding was used, however, Dana Walsh remained defiant, even mocking her torturer. Jack arrived at the location - accompanied by Walsh's fiancee, Cole Ortiz - in time to stop the planned execution of Dana, killing Bledsoe and his men in the process.

Pharmaceutical interrogation Edit
Pharmaceutical interrogation is torture conducted with pain-inducing chemicals in an attempt to gain information from a suspect. This has been used on many people, including Nina Myers in Day 3, Christopher Henderson in Day 5, Audrey Raines in Day 5 and Chloe O'Brien in Day 9. A overdose of these chemicals will lead to death, Tony Almeida seemed to be killed with an overdose (though it is later revealed in Day 7 he was revived within minutes).
In this type of torture, there is a chemical called hyoscine-pentothol that is commonly used.
Psychological interrogation Edit
Psychological interrogation is a form of torture that utilizes manipulating a source's mind in order to extract information. Sensory deprivation treatment (SDT) is a form of psychological interrogation.

Day 8 Edit
- Marcos Al-Zacar: was interrogated over a video feed by Jack Bauer in order to make Marcos think twice about detonating his suit's pack of explosives.
Background information and notes Edit
- Torture is widely considered an immoral practice, and 24 has been accused of promoting the use of excessive violence and torture in the minds of the voting public, in part to support the policies of former President George W. Bush's federal government. However, it is used by the creators of the show in an apolitical delivery to simply illustrate a dramatic outcome for the various characters in the show.
