There is enough evidence that someone has committed a crime serious enough to warrant being taken into custody (police detention).
In such a situation, law enforcement officers would need to gather sufficient evidence to establish probable cause, which is a legal standard required to justify an arrest. This evidence may include witness statements, physical evidence, surveillance footage, or other pertinent information that points to the individual's involvement in the crime.
Once probable cause is established, police officers would have the authority to take the suspect into custody and formally charge them with the offense. The suspect would then be informed of their rights, such as the right to remain silent and the right to legal representation.
It is important to note that the individual being taken into custody is presumed innocent until proven guilty in a court of law. The suspect would have the opportunity to present their defense and challenge the evidence against them during legal proceedings.
Overall, the decision to take someone into custody is not made lightly and is based on the available evidence and legal standards that must be met to justify an arrest.
