Indie rocker Matt Berninger recently sparked a massive security scare at an airport in Hawaii when he tried to bring a fake bomb clock back to America from a trip to Japan.

The National frontman was relaxing at Honolulu Airport when he was called to the security desk.

Unfortunately, the jet-lagged singer didn't respond to the request right away - and, by the time he did, staff had started to evacuate.

He tells, "I had bought a novelty clock in Tokyo, some sort of goofball alarm clock that happened to look exactly like a bomb. And it was in my suitcase.

"I had the Honolulu Airport evacuated for about 45 minutes. I ultimately had to surrender the alarm clock... but they (security) were very pleasant and professional. They had done a great job and I thanked them and they let me go."
