Twenty-five criminal underage drinking citations were made on Saturday night after Maricopa County Sheriff's deputies did an undercover operation at a motorcross race track.
MCSO also said in a release that there were five DUI arrests, two drug arrests, 15 civil traffic violations and six arrests on criminal warrants made at Speedworld Raceway Park in Wittmann, Ariz.
"Underage drinking is a serious problem and somebody out there is obviously selling alcohol to these kids. We're going to find out," said Sheriff Joe Arpaio.
The sheriff's office was provided images of underage drinking and other activities with boys as young as 12 there.
Speedworld released the following statement on Tuesday via their public relations firm, Rose+Moser+Allyn.
"We would like to get to the bottom of this as much as anybody. We do not sell alcohol on the premises nor do we possess a permit to do so. We don't think this is a widespread or consistent issue but anytime there are arrests for something of this nature, it obviously gets our attention. Although we already have robust security on the grounds, out of an abundance of caution we are re-evaluating our security presence and will take the appropriate next steps. We want to ensure that fans come to Speedworld and enjoy motor sports in a safe and legal manner."
