NEWTON FALLS, Ohio - Two suspects plead not guilty to federal charges after police and Homeland Security investigators arrest them at  home in Newton Falls.

Local police and federal agents confiscated boxes of evidence on Wednesday during a search of a home at 31 East Church Street.

Ryan Kralik and Ruth Eimers entered the pleas during  initial appearances in U.S. District Court in Youngstown on Wednesday.

A six count federal indictment charges the two with  possession of synthetic bath salts.

The indictment says that the chemicals are a considered a controlled substance that can have a stimulant, depressant or hallucinogenic effect on the central nervous system.

The two allegedly operated a web site, Freshsalts.com, which offered the synthetic bath salts for human consumption.

The indictment says the web site sold the substances under the names, "Eightballz Extreme," Tranquility," "8Ballz of fire" and others.

The U.S. Attorney's office claims the suspects tried to conceal the true purpose of the synthetic bath salts by labeling them as "glass cleaner," bowling ball cleaner," or "stain remover."

Kralik and Eimers allegedly sold bulk amounts of the salts for prices ranging from $299 to $459.

Homeland Security  investigators are involved in the  case because Kralik allegedly imported some of the chemicals from the People's Republic of China.

Kralik remains in custody pending a detention hearing next week.

Bond for Elmer was set at $25,000.
