Federal agents and local police raided a Roswell home Tuesday afternoon, looking for human growth hormone and other drugs, authorities said.

The drug-making operation — selling HGH, testosterone, and copy-cat versions of Cialis online and through mail-order — netted an estimated $25,000 to $30,000 a day, said Roswell police Lt. James McGee.

"We got a tip about three or four months ago," McGee said. "We found it was more far-reaching than we initially thought."

Agents from the investigative wing of the Food and Drug Administration joined Roswell S.W.A.T. officers late Tuesday afternoon to go into the house.

A Roswell couple is being held for questioning, McGee said, and charges are likely to come from the FDA.

Agents and police were still searching the house at 6:30 p.m. as part of the investigation, McGee said.
