4 arrested in OKC, accused of mailing fentanyl to jail

Four people are in custody, accused of mailing fentanyl to the Oklahoma County Jail, according to authorities.

Jail investigators, assisted by the Oklahoma County Sheriff's Office, executed a search warrant near SE 14th St. and South Bryant Avenue, leading to the arrest of four suspects.

Investigators on scene said they found evidence of drugs in the home, including a meth lab. They said five people were taken into custody from the house, with at least one being taken to jail due to a warrant.

Authorities said 60 grams of fentanyl was sent to the jail, which they said was enough to kill 30,000 people.

The investigation is ongoing.
