Hingis says she is accused of testing positive for cocaine; retires from tennis
 

ZURICH, Switzerland (AP) -- Martina Hingis said Thursday she has been accused of testing positive for cocaine at Wimbledon, and then announced her retirement from professional tennis.

Hingis, a five-time Grand Slam champion and former Wimbledon winner, denied using cocaine.

"I find this accusation so horrendous, so monstrous that I've decided to confront it head on by talking to the press," she said. "I am frustrated and angry. I believe that I am absolutely 100 percent innocent."

Her voice broke as she fought back tears in reading the statement. At the end, she took no questions and left the news conference.
