A Bradenton man remains in jail for allegedly selling an addictive drug to undercover officers.

The sheriff’s office arrested 31-year-old Kirby Riley yesterday.

Authorities say Kirby yesterday sold the undercover office a hundred dollars in Fentanyl.

Some consider this highly-addictive opiate prescription drug more deadly than heroin.

Riley’s charges include possession and sale of a controlled substance within a thousand feet of a church.
