The Austrian Olympic Committee said Tuesday it received a letter stating that two of its athletes would be kidnapped during the Winter Olympics, which will be held from Feb. 7 to Feb. 23 in Sochi, Russia.

"The letter was immediately handed over to Interior Ministry officials in Vienna so they can investigate. Currently, any serious threat against our security has been ruled out," the committee said in a statement.

The targets of the threats are skier Bernadette Schild and skeleton pilot Janine Flock.

Initial reports said the skier threatened with abduction was Marlies Schild, Bernadette's older sister.

The 32-year-old Marlies Schild has won three Olympic medals and is one of the great hopes of the Austrian team competing at the Sochi 2014 Games.

Only four people knew about the anonymous letter and it has not been determined how the information was leaked to the press, Austrian Olympic Committee secretary-general Peter Mennel told the APA news agency.

Mennel said he discussed the letter with Flock on the flight Tuesday from Vienna to Sochi.

Flock "is not worried" and is confident about security at the Olympics, Mennel said.

Two Austrian police special operations officers will accompany the athletes to Sochi and whenever they venture out of the Olympic Village, Mennel said.

The Austrian security service is investigating the letter and the Interior Ministry has not provided additional information about the measures being taken to protect athletes. EFE
