A man suspected of trying to use a fake prescription to get codeine syrup at a Walmart pharmacy March 21 is the subject of an Oakwood Police investigation.

Authorities said the suspect, believed to be a black man in his late 20s standing around 5 feet. 9 inches tall and between 170 and 180 pounds, had a prescription with a fake clinic and patient name.

The prescription did, however, “contain a legitimate physician name who works in the emergency room at a local hospital,” according to an Oakwood police news release.

The suspect was last wearing a Nike long-sleeve sweatshirt and a baseball cap, authorities said. He left the parking lot with an unknown person in a dark-colored Mustang convertible.

Oakwood police are asking pharmacies to be vigilant about anyone using counterfeit prescriptions to obtain promethazine codeine syrup.

Anyone with information is asked to call 911 or their local police department.
