Video from AIR7 HD appeared to show first responders talking to the man as he sat along a ledge high above the front entrance of the Dolby Theatre, which faces Hollywood Boulevard. The busy street was closed to all traffic shortly after 10 a.m. as the tense situation unfolded.
A large white and yellow air cushion was set up on the ground some 60 feet below the area where the man was located.
Mental health professionals were summoned to the scene, the Los Angeles Fire Department said.
