A Pittsburgh man is accused of selling fentanyl to a police informant last year in Butler Township.

The state police vice unit Wednesday charged 25-year-old Charles W. Cox with a felony count of delivery/possession with intent to deliver a controlled substance, and misdemeanor counts of possession of a controlled substance and drug paraphernalia.

Police said they used an informant for a controlled drug buy June 22, 2020. The informant and Cox agreed to meet at a prearranged location in Butler Township, police said.

Officers surveilled the meeting, investigators said, with the informant getting into the back of the defendant's vehicle. The informant later turned over to officers several bundles of heroin/fentanyl allegedly purchased from Cox.

Police subsequently sent the drugs to their crime lab in Westmoreland County. Lab tests found that the drugs tested positive for fentanyl, police said.

Cox's arraignment is pending. Online court records did not list an attorney for him.
