<p>SAN FRANCISCO—A bomb scare on Wednesday caused the evacuation of two technology conferences being held at the Moscone Center here, sending about 14,000 attendees onto the nearby streets and sidewalks.</p>
<p>After searching the emptied convention center for about two hours, San Francisco police said they had found no indications of a bomb and cleared the center for re-entry at 4:20 p.m. Pacific time. The evacuation cancelled the OracleWorld and the Seybold Seminars San Francisco 2003 conferences for the rest of the day, and managers of both shows said they planned to resume their conferences on Thursday morning.</p>
