A security guard has been dispatched to an incident where a serious criminal offence has occurred. What should the security guard's first response be?

The most appropriate first response for a security guard dispatched to an incident involving a serious criminal offense is to close and cordon off the area. This action is crucial for several key reasons.

Firstly, cordoning off the area serves to preserve the scene of the crime, which is essential for law enforcement agencies to conduct their investigation effectively. It prevents contamination of physical evidence that could be critical for solving the case and ensures that the area remains secure until the police arrive.

Secondly, securing the location helps protect potential witnesses from leaving the scene and allows the guard to manage the situation until law enforcement takes over. This approach aids in maintaining order and safety within the vicinity of the incident.

While interviewing witnesses is important, it should be conducted after the area has been secured. Engaging with witnesses requires the guard to prioritize preserving evidence and ensuring that no one inadvertently disturbs the scene. The safety of the security personnel, the public, and the integrity of the scene must be the primary focus at the outset of such incidents.
