Introduction

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.

That being said, the law should not "unduly hamper" the police in criminal investigations.[1]

Distinction Between Detention and Arrest

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.[2]

State Agency

The law relating to detention and arrest concerns the conduct of peace officers. 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]
