DOVER — Three men were indicted separately Monday as the result of an investigation into alleged methamphetamine manufacturing in the Felton area earlier this year, according to court documents.

Michael W. Baker, 24 at the time of his arrest in February, was indicted on charges of operating a clandestine laboratory, drug dealing, illegal possession of a controlled substance, possession of drug paraphernalia and possession of a deadly weapon during the commission of a felony by person prohibited. A shotgun was referenced in court documents filed by a Kent grand jury.

Christopher G. Divel, 25, of Houston, was indicted on drug dealing and second-degree conspiracy charges.

Todd S. Plummer, 33, of Greenwood, was indicted on charges of operating a clandestine laboratory, drug dealing, second-degree conspiracy, illegal possession of a controlled substance and possession of drug paraphernalia.

When announcing the arrests, police said Governor’s Task Force members, along with a probation and parole officer, first went to the 4600 block of Hills Market Road to execute an administrative probation check on Mr. Baker on Feb. 10.

The check followed Mr. Baker’s earlier shoplifting arrest from the Lowe’s in Camden, where items common to methamphetamine were involved, police said.

According to authorities, Mr. Baker, Mr. Divel and Mr. Plummer were seen standing in a detached garage on the property and taken into custody without incident.

A search ensued, police said, and equipment and component mixtures connected to methamphetamine manufacturing were located. Inside the residence, three shotguns and two rifles and ammunition were found, according to authorities.

Deputy Attorney General Zach George signed the indictment for the state of Delaware.
