Karl "Jack" Frost, Arrested After His "Citizen's Arrest" of Jogger, Struggles With "Inner Demons;" Rages in 911 Call

Karl "Jack" Frost, who tried to make a "citizen's arrest" of a jogger last week in Gilbert, told police he struggles with "inner demons" now that he's no longer a police officer.

Frost believes he was right to restrain the 52-year-old jogger, but police arrested him after the morning dust-up on suspicion of unlawful imprisonment and other charges.

His explosive anger can be heard in a recording of the call he made to 911 while holding on to the victim. Check out the call at the bottom of this post.
