About to run in the 100 meters? Doesn't matter — get in line.

Usain Bolt was left baffled by London's rigid security rules on Sunday night as he made his way to the stadium for his race.

"I was in the line, we were waiting to run and the guy was telling me to line up straight," Bolt said. "I was like, 'Really? We're about to run and they are going to make me stand in a straight line?' There are just some weird rules here."

Such as not being allowed to get skipping ropes past security.

"They said I can't bring it in, and I asked, 'Why?'" Bolt recalled. "They just said it is the rules. So if I have a rubber band that I need to stretch, I can't take it in. And when I asked why, they say, 'It's just the rules.'

"It's just some weird small rules that don't make any sense to me, personally."

Games organiser Sebastian Coe says there will be an investigation, but joked Monday that the delay "didn't seem to slow him up too much."
