(St. Cloud, MN) -- A St. Cloud business owner has been arrested on several charges stemming from an undercover drug investigation. Law enforcement officials used a search warrant Monday at the IPOD Guy Store. The search stemmed from two undercover drug buys at the store where owner, 44-year-old Andrew Fredrick, allegedly sold officers prescription drugs. Police seized Oxycontin and Percocet pills at the store Monday and arrested Frederick. A 17-year-old girl and an 18-month-old child were also at the store. The girl told police she was Frederick's girlfriend and the child was hers. Police used a DNA test to determine the child was Frederick's and that the child was conceived when the girl was 15-years-old. Police also seized a .40-caliber handgun in the raid.
