Answer:
The confession is accepted as a voluntary statement.
Step-by-step explanation:
As seen in the question above, a man went, of his own free will, to a police station to confess to a crime he had committed. He had killed someone, the confession was recorded to be used in a possible trial, however the man was arrested as he committed a crime.
This statement must be accepted as a voluntary statement. This was because the man was not declared a suspect in a crime, he was not in custody and he was not being questioned.
