LOS ANGELES, California (CNN) -- Fans must register online for a lottery to win tickets to the Michael Jackson memorial Tuesday at the Staples Center in Los Angeles, organizers said Friday.
People who do not have one of the 17,500 free tickets to be handed out should stay away and watch the event on television, the Los Angeles acting mayor, Jan Perry, and a Los Angeles police official said.
Jackson family spokesman Ken Sunshine said no details would be released Friday about what fans will see at the memorial.
"It's still be being developed," Sunshine said about the Jackson memorial.
Eleven thousand tickets will be for seats inside the Staples Center. Another 6,500 will be for the Nokia Theatre next door, where the service will be broadcast.
To register for a ticket, patrons are being asked to go to staplescenter.com.
