Arrest and Detention

The police powers of detention and arrest are some of the most important powers available to a peace officer in their investigation of criminal activity. It is also some of the most invasive powers upon a person's liberty. This is a classic issue of procedural law that circumscribes the peace officers authority in these matters.

These chapters cover not only the powers of police to detain or arrest, but also the right a person has when the police engage in such conduct and remedies for breaches of those rights.

The transition from investigative detention to arrest and search is a fluid and dynamic process in situations such a traffic stop. It is not to be segmented into discrete parts.[1]

In general terms, the law should not "unduly hamper" the police in criminal investigations.[2]

State Agency
Arrest and detention by private security on the basis of committing a criminal offence and then delivery to the police does not amount to state conduct.[3]
