From my friend, Don Barrett of LARadio.com:
KNX is simulcasting KCBS-San Francisco because all employees have been evacuated from their Miracle Mile building due to bomb scare
UPDATE: 10: 01 AM PDT:
KNX's Pete Demetriou is reporting that hundreds of workers in the CBS building have evacuated the Miracle Mile headquarters and are standing a half block to a block away. "The suspicious package is in the mailroom, which is in the core of the building, right near the central elevator shafts. They will have to go inside the building to get a look at what is causing the problem."
Scott Ramsay sent an email about a half hour ago: "Bomb Squad just passed me North bound on La Cienega at Centinela."
UPDATE 2: All Clear in LA
The KNX GM is waving to all employees gathered around the Miracle Mile building on Wilshire Blvd to return and come on back.
Bomb scare was a ticking clock.
