Oscars Structure Collapse Injures 5

March 23 -- Terror interrupted excited preparations for Sunday's Academy Awards ceremony when a scaffolding built near the red carpet area in front of Los Angeles' Shrine Auditorium collapsed Thursday. Five people were injured in the accident, according to fire officials.

The cause of the structure's collapse is still being investigated, but some bystanders told Variety a breeze may have triggered the incident by blowing a net into the bleacher area.

Two people were on the scaffolding when it tumbled, while two others were working underneath. A fifth person was hurt trying to flee the bleachers — which hold journalists and other Oscar watchers at bay as celebs arrive at the gala event — when the scaffolding collapsed.

According to Variety, one worker received neck and back injuries, while others had minor cuts and bruises. Some of the workers fell 20 feet to the ground when the structure crumbled.

"It will not delay the ceremony at all," said John Pavlik, spokesman for the Academy of Motion Picture Arts & Sciences at a press conference late Thursday. "We actually were a little bit ahead of schedule today, so we are not terribly concerned about getting back on schedule."

The Academy Awards will be broadcast on ABC at 5 p.m. PST on Sunday.
