What documentation must police provide after a person is detained?

The correct answer, which is a written notice explaining the reasons for detention, aligns with the legal obligations placed on police when detaining an individual. According to New South Wales law, particularly under the Law Enforcement (Powers and Responsibilities) Act, when a person is detained, the police are required to inform them of the reasons for their detention in a clear and documented manner. This written notice serves as an essential part of ensuring transparency and accountability in the policing process, allowing the detained individual to understand the circumstances leading to their detention.

Providing a verbal explanation of rights alone does not fulfill the legal requirement for formal documentation. Similarly, while offering a form for legal representation or a summary of previous arrests may be useful, they do not meet the specific statutory requirement regarding the notice of reasons for detention. The emphasis on a written notice not only protects the rights of the individual but also provides a clear record that can be referred to later in any ensuing legal processes.
