The arson investigation into a fire that erupted at a back lot at Universal Studios in Universal City on Friday night has been put on hold until Tuesday because one of the destroyed buildings is too dangerous to enter.
"It's a safety problem," Sheriff's Sgt. Ron Moya said. "We don't want to get our investigators in there and have the roof and walls come down on us."
Investigators are attempting to determine whether a bomb threat received by the studio shortly before the fire started about 7:40 p.m. is linked to the blaze.
"We certainly are going to look into that to see if it could be tied in to the original incident," Moya said.
