What information is typically required for a witness statement under the Criminal Procedure Act?

A witness statement under the Criminal Procedure Act must be written in a language that the declarant, or the witness, understands. This requirement ensures that the witness can accurately convey their observations and experiences regarding the matter at hand. If the statement is not in a language understood by the witness, it may lead to misunderstandings or inaccuracies in the information provided, compromising the integrity of the statement.

In this context, the other options do not align with the essential requirements for a witness statement. Family history, proof of residency, and civic engagement history are not typically relevant to the validity or effectiveness of a witness's testimony. The focus is on the clarity and comprehension of the statement itself, emphasizing the importance of the declarant's understanding in the legal process.
