Federal narcotics agents raided a Kaiser Permanente pharmacy in North Portland with a warrant Tuesday morning.

Agents with the U.S. Drug Enforcement Administration executed an administrative inspection warrant at Kaiser Permanente Interstate Medical Office on North Interstate Avenue, said Cam Strahm, assistant special agent in charge at the agency’s Oregon office.

Federal narcotic enforcement officers from the agency’s diversion control office use administrative warrants to obtain records to determine if legitimately-made controlled substances are being diverted from their lawful purpose into illicit drug traffic.

Portland police officers assisted, but the Police Bureau isn’t directly involved, said Portland police Sgt. Brad Yakots.

The inquiry is part of a Los Angeles-based investigation. Kyle Mori, the DEA spokesman from Los Angeles, did not return calls.

Mike Foley, a spokesman for Kaiser Permanente, said in a statement Tuesday afternoon, "Today the Drug Enforcement Administration performed administrative inspections at several Kaiser Permanente pharmacies located throughout the organization. We are fully cooperating with the DEA to provide the agency with the information they are seeking. As always, we are committed to complying with all state and federal regulations and ensuring the safety of our patients and members. ''
