The murdered was arrested by the policeman.

• This voice describes interest in the element that experiences a change, instead of the element that is performing the change.
• When the emphasis is on either the thing or the person affected by the action, it is used.  
• It generally uses the word ed and receives the verb action.
• For example -  Active: Roy reads a novel.   Passive: A novel is read by Roy
• Thus, the correct sentence is - The murdered was arrested by the policeman.
