The call came in to the station shortly after 6 p.m. that there were multiple packages on the lot with explosive devices. Police and bomb squad units responded and evacuated the station operations as well as other soundstages and buildings on the lot in the 5800 block of Sunset Boulevard.
KTLA was in the midst of a 6 p.m. newscast when the bomb squad began its sweep of the lot. The station finished the newscast and made no mention of the incident on-air. About 100 KTLA staffers were at work at the time. Staffers were allowed back into the building at aroudn 8:35 p.m.
The apparent hoax targeted at KTLA came on the heels of the devastation caused by two explosions Monday at the Boston Marathon that left three dead and more than 140 injured.
The KTLA lot is also home to numerous stages where non-KTLA shows are produced, though few if any shows were believed to be in production at the time of the bomb scare.
Los Angeles Police Officer Christopher No said police determined that the call was a “prank” that came into the station through a relay device. An investigation is ongoing, No said.
