The revelry at the Electronic Entertainment Expo temporarily paused Wednesday afternoon after an unidentified man suffered a seizure and fell down an escalator at the Los Angeles Convention Center.

The entrance leading down to the venue's South Hall lobby was closed off as emergency personnel assisted the wounded E3 attendee.

The man suffered head trauma and was initially unconscious and bleeding at the base of the elevator as frantic convention goers sought help from nearby security personnel.

The man was revived then transferred to an ambulance. The escalators remained closed as a cleaning crew later worked to clean up the scene.

A spokesman for the Electronic Entertainment Association, which organizes E3, said the man was a staff member and is recovering after his injuries.

The annual gathering of the video game industry draws over 50,000 game developers, reporters and other industry insiders to the Los Angeles Convention Center for previews of upcoming software and hardware.
