Police arrested a Roswell couple Wednesday afternoon following a search of their home the day before for evidence of a nationwide mail-order drug operation.

Christian Navoy, 36, and his wife Jennifer Navoy, 34, were arrested on federal warrants by Roswell police in a bank parking lot. It was unclear late Thursday what charges they faced and whether they still were being held.

Federal authorities believe the couple were selling steroids as well as drugs for erectile dysfunction without a permit from the Federal Drug Administration, said Roswell Police Lt. James McGee.

The Navoys appeared not to have regular jobs, and the drug operation netted them about $25,000 to $30,000 a day, McGee said.

Federal authorities seized the couple's cars – a Hummer, a Lotus and a Jeep — and were planning to seize their home, valued between $700,000 and $1 million, McGee said.

The operation was Internet-based, and orders were delivered through the U.S. mail, he said. The arrest was part of a three-month investigation by the Federal Drug Administration, the U.S. Postal Inspector's Office and Roswell police. The investigation is continuing.
