DED No Contest

[billk5300s]

Yesterday after an extremely long tote delay the officials at Delta Downs declared the 4th race a \"no contest\" and refunded all wagers.  There were no spills or incidents other than what appeared to be a tote problem.  I don\'t recall ever seeing anything similar happen before.  The remainder of the card was run without any issues.  Has anyone heard anything regarding this?  It seemed very odd. I had seen a story regarding over seas tote manipulation and wondering if this incident may have been related....
