Laurel County deputies went to a home to serve a federal indictment warrant on an East Bernstadt resident, and they ended up also arresting three others on drug charges.
It happened Monday morning on Helton Road, about five miles north of London, the Laurel County Sheriff's Department said.
The department's special response unit, along with representatives from the U.S. Marshals Service, went to arrest James Helton Jr., 55, of East Bernstadt. He had been indicted on federal charges that included conspiracy to distribute methamphetamine and possession of firearms by a felon.
Deputies also arrested three others who allegedly were involved in drug trafficking, the sheriff's office said.
Melissa Helton, 33, and Carl Helton, 53, both of East Bernstadt, were charged with first-degree trafficking in meth and possession of drug paraphernalia. Debra Vaughn, 33, of London, was charged with trafficking in methamphetamine, possession of drug paraphernalia, and being a persistent felony offender.
All four suspects were being held in the Laurel County jail.
An investigation is continuing, the sheriff's department said.
