The necessity of an arrest is justified under Section 24(5) of the Police and Criminal Evidence Act (PACE) primarily to prevent a suspect from disappearing. This reasoning is grounded in ensuring that individuals who may be involved in criminal activity cannot evade law enforcement, which would hinder the investigation and prosecution process. The act recognizes the importance of maintaining the integrity of the judicial process, as allowing a suspect to evade arrest could result in the loss of critical evidence, witness testimony, or a complete breakdown of the case. Collecting evidence is indeed a vital part of any investigation, but it does not inherently justify an arrest. Protecting against property damage is significant too, but it is not specifically outlined as a reason for arrest in this context. Furthermore, issuing a fine pertains more to punitive measures rather than the grounds for arrest in a criminal context. Therefore, the correct choice highlights a central concern of law enforcement in ensuring that suspects remain available for questioning and further legal proceedings.
