Peter Thomas, 35, of Villa Park faces four felony drug charges after allegedly selling methamphetamine to an undercover Elmhurst police officer on three occasions, according to the DuPage County State's Attorney's Office.

Officers arrested Thomas on Wednesday, Oct. 28, at a business in the 100 block of West First Street in downtown Elmhurst. Prosecutors alleged they found a baggie containing approximately 29.48 grams of methamphetamine in his pants pocket, Patch reported.

That's roughly an ounce of meth.

The Elmhurst Police Department, working with the Chicago Police Department, identified Thomas as an alleged source of methamphetamine sales in the DuPage County area, according to the state's attorney's office. On Aug. 31, an undercover officer contacted Thomas and arranged to buy an eight-ball of meth the following day, prosecutors alleged.

The first sale took place Sept. 1 at the West First Street business, where the officer purchased approximately 4.26 grams for $40, according to Shaw Local. The undercover officer then made two more purchases from Thomas at his home: approximately 3.27 grams on Sept. 30 and approximately 7.33 grams on Oct. 28, prosecutors alleged.

After the Oct. 28 sale at his home, Thomas drove to the West First Street business in Elmhurst. Officers arrested him as he got out of his car, police said.

Thomas is charged with three counts of delivery of methamphetamine, one count of possession with intent to deliver methamphetamine, one count of misdemeanor resisting a police officer and one count of misdemeanor unlawful possession of cannabis by a driver. Shaw Local reported the possession-with-intent count is a Class X felony, citing the state's attorney's office.

DuPage County State's Attorney Robert Berlin said in a statement that drug dealers "profit on the suffering and heartbreak of others and care only about lining their pockets at society's expense."

A DuPage County judge denied prosecutors' request to hold Thomas in jail until trial. He was released with conditions barring him from possessing or consuming alcohol, cannabis or any controlled substances not medically prescribed, prosecutors said. He must also submit to testing.

Thomas appeared in court Oct. 29. His next court date is Nov. 23.
