Washington, April 16 : High School Musical actor Zac Efron has offered his apologies to an airport security guard after he fell on top of him while running away from the paparazzi.

The 21-year-old heartthrob revealed he had been running run up and down an escalator to escape tailing photographers when he tripped, fell and landed on security guard who was trying to help him.

"There were so many paparazzi. It was crazy. When there’s that many paparazzi, you can’t see. People start yelling. People get hurt,” Contactmusic quoted him as saying.

"While I was running, the guy in front of me kind of fell and then I fell on top of him. It was kind of weird.

“The guy was not a bodyguard - he was just a guy from the airport helping out. I felt terrible," he added. (ANI)
