June 13 (UPI) -- A woman is in critical condition after a shark attack at a popular Sydney beach Saturday, and she was saved by a nearby lifeguard.

The 35-year-old woman hasn't been identified. She had serious bite injuries on a leg and an arm from the morning attack at Coogee Beach, a police statement said. She and two friends were swimming about 100 feet from the shore, when she was bitten, ambulance official Michael Corlis said. Lifeguard Tony Waller said the shark was about 11 feet long.

Lifeguard Charlie Verco told The Sunday Telegraph in Sydney that he saw the shark while he was on his paddleboard.

"I saw the shark come out of the water and just the size of it shocked me," Verco said. "I kept paddling towards her and the shark took her underwater and I was going, 'What do I do now?' A couple of seconds later, she popped up again."
