Arnold was sworn in as an officer in May 2009 and has been involved in five accidents since then. In the last crash, Arnold was reaching for a drink and following another officer’s car too closely and swerved off the road to avoid a collision.

Arnold’s attorney, John Kopack told the Northwest Indiana Times that Arnold has good grounds for an appeal.
