Australian singer Guy Sebastian's day at the beach over the weekend (14-15Sep13) was ruined when criminals swooped in and stole his possessions while he was in the sea. The star was enjoying a day surfing at Santa Monica, Los Angeles when he returned to the beach to find his clothes and car keys had been taken by thieves. He tells the Sydney Daily Telegraph, "I was at the beach trying out my new board and trying to keep an eye on my stuff. "When I came back in someone had flogged my towel, my shorts, my old T-shirt and stolen my car keys. I had to get a tow truck out and call a friend for help." Sebastian has been the victim of theft several times in recent years - he fought off a would-be burglar at his home in Sydney last year (12) and was robbed of $150 (£100) cash at knifepoint by thieves in the U.S. in 2009.
