A man identifying himself as a police officer appears to have exploded in a rage of vulgarity and other verbal abuse during an alleged assault on a 21-year-old man at a West Valley City gym, according to a 911 tape.
The tape, which lasts more than five minutes, reveals the man swore at the victim repeatedly and threatened to take him to jail.
