     Brave Frenchman Found Halfway Around the World

     (NEW YORK)A French tourist highly praised for rescuing a twoyearold girl in Manhattan said he

didn't think twice before diving into the freezing East River.

    Tuesday's Daily News said 29yearold Julien Duret from France is the man who left the spot quickly

after the rescue last Saturday.

    He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum.

He handed the girl to her father, David Anderson, who had dived in after him.

    “I didn't think at all, ”Duret told the Daily News.“It happened very fast.I reacted very fast.”

the river.In an instant, he took off his coat and jumped into the water.

    When he reached the girl, she appeared lifeless, he said.Fortunately, when she was out of the water,

she opened her eyes.

    Anderson said his daughter slipped off the bank when he was adjusting his camera.An ambulance

came later for her, said Duret, who was handed dry clothes from onlookers.Duret caught a taxi with his

girlfriend shortly after.

  The rescue happened on the day before he left for France.Duret said he didn't realize his tale of heroism
