FBI looks for links in David Letterman, Craig Ferguson threats
On Tuesday. two employees opened the letter at the CBS-TV studios in the 7800 block of Beverly Boulevard before taping of Ferguson's "The Late Late Show," the Los Angeles Police Department said.
Detectives from the LAPD's Major Crimes Division were investigating with the FBI and authorities in Europe, where the letter was believed to have originated, officer Karen Rayner said.
Earlier this month, an Internet jihadist threatened to cut out Letterman's tongue.
A contributor on a website using the name Umar al-Basrawi posted his threat in response to the late-night host's comments about the early June death-by-airstrike of Ilyas Kashmiri, Al Qaeda's alleged new leader after U.S. Special Forces killed Osama bin Laden in Pakistan earlier this year.
