SALT LAKE CITY?House cleaners found used blood transfusion bags at a home where Austrian Nordic skiers stayed during the Winter Olympics.

The bags were found Wednesday along with blood transfusion sets, glucose bottles and vitamins. All evidence was turned over to doping control officials for the Salt Lake Organizing Committee.

Doping officials are analyzing blood residue for signs of banned substances.

The Austrians took home three Olympic medals in Nordic events. Christian Hoffmann won a silver and Mikhail Botvinov bronze in the 30 kilometer race, while Wolfgang Perner won bronze in the 10 kilometer biathlon sprint.
