The Food and Drug Administration is investigating an alternative cancer treatment center in south Tulsa.
The FBI tells FOX23 News agents served a search warrant at Camelot Cancer Care, Inc. on Tuesday. The center is located in an office building near 71st and Yale.
A man who works in the building tells FOX23 he saw several police cars and FBI agents carrying boxes out of the building, “the building manager told us we were in no danger, we didn't need to evacuate, we didn't need to lock our doors or anything."
Camelot Cancer Care’s website says it uses natural substances approved by the FDA to treat cancer without the toxic effects of chemotherapy and radiation.
The FBI confirms the FDA is handling the investigation, but neither agency would comment about it.
One man, Michael McDonnough, was arrested during the investigation. According to the arrest report he left the building when federal agents told him to, but then returned to the office secretly and tried to remove a computer. The report says when agents stopped him he refused to hand over the computer and shoved one of the agents into a wall.
After the fight McDonnough was taken into custody and a gun was found in his backpack.
