DOVER — Four arrests were made Friday to cap an investigation into alleged methamphetamine at a residence, authorities said.

Dover Police said a search warrant execution in the 2000 block of White Oak Road at 6 a.m. yielded the alleged discovery of a clandestine laboratory and components to manufacture methamphetamine.

City police officers, Dover-based Drug Enforcement Agency agents, the DNREC Emergency Response Unit, and Little Creek Fire Company all took part in the operation. No neighborhood evacuations were necessary, spokesman Master Cpl. Mark Hoffman said.

Gordon L. Clark Jr., 25, of the 2000 block of White Oak Road, was charged with possession of drug paraphernalia and violation of probation.

Husband and wife David P. and Vivian Loder, both 36, of the 2000 block of White Oak Road, were charged with operation of a clandestine lab, second-degree conspiracy, possession of drug paraphernalia and maintaining a drug property.

Clark S. Rholetter, 50 of the 100 block of Front Street in Leipsic, was charged with operation of a clandestine lab, second-degree conspiracy, and possession of drug paraphernalia.

After arraignments through JP Court 2 in Rehoboth Beach, the cases were transferred to the Kent County Court of Common Pleas.
