Two Kaiser Permanente facilities in Oakland were closed this morning because of a "specific and credible criminal threat," police said.
Kaiser officials said in a statement that the two facilities -- office buildings at 3600 and 3701 Broadway -- would remain closed until 12:30 p.m. today as police investigate the threat.
Kaiser initially said that the closure would stay in effect until 11 a.m. today and again on Wednesday but then clarified that it would be until 12:30 p.m. today and no closure is expected Wednesday.
The closure affects offices, clinics, laboratories and pharmacies as well as the parking garages adjacent to the two buildings, Kaiser officials said.
Kaiser is contacting patients that had appointments at the buildings or prescriptions to pick up to reschedule and will extend hours to accommodate the schedule changes.
The closures are not affecting the Kaiser Permanente hospital or emergency room.
Oakland police Officer Frank Bonifacio provided few details on the specific threat, but said that Oakland police are working to identify who made the threat.
