LOS ANGELES -- A suspicious package has forced the evacuation of the offices of Los Angeles all-news radio station KNX.

The station's news anchors announced just before 9 a.m. Tuesday that they had been ordered to leave their Wilshire Boulevard newsroom and studio because of a suspicious package discovered in the building.

The 50,000-watt station switched listeners to the broadcast feed of its sister station, KCBS radio in San Francisco.

Los Angeles police spokesman Richard French says a suspicious package that was beeping was found in the lobby area on the building's second floor.

Firefighters and police responded and the bomb squad is expected to be dispatched.

Further details are not immediately available.
