Authorities are reviewing security protocols at a Ronald V. Dellums Federal Building in downtown Oakland after a bullet was found lodged in a judge's jury room.
Deputy U.S. Marshal Joseph Palmer, a spokesman for U.S. Marshal Don O'Keefe, said the bullet was found Saturday afternoon when no one was in the building. Palmer said it it went into the window on the second floor of the federal courthouse before stopping in the jury room.
Palmer said it doesn't appear that any judges or staff were targeted.
Investigators are looking into whether the bullet was a stray, fired during a shooting that occurred about 1:30 a.m. Friday when someone was shot and wounded about a block away.
(Correction: An earlier version of this story said the bullet passed through a judge's chambers. U.S. Marshal Palmer tells NBC Bay Area the bullet never passed through the judge's chambers.)
