The day before the anniversary of the September 11 2001 terrorist attacks, a series of bomb threats directed at the Moscone Centre in San Francisco put the OracleWorld 2003 database users' show on hold.
According to a San Francisco Police Department spokesman, three or four anonymous bomb threats were called in Wednesday at around 1:20 p.m. PDT, after which police contacted Oracle executives about the threats. They also dispatched a number of police officers and a mobile command vehicle to the centre.
About an hour later, at the order of Oracle Executive Vice President Chuck Phillips, an announcement was made that the 14,000 or so show participants had to be evacuated, and sessions were canceled. No reason was given.
No one was hurt during the 10-minute evacuation, which was "very orderly," according to an Oracle spokesman. He said the decision was made in "the best interest of the safety of the attendees."
The San Francisco Police Department made a sweep of the centre, and the threat was proved to be false. The centre was declared safe at about 4:20pm, the police spokesman said.
According to Oracle, the show resumes Thursday, but with heightened security measures.
The police said the source of the threats is unknown.
