AUSTIN, Texas -- Federal investigators have subpoenaed documents from a 2004 arbitration case in which a Dallas-based company tried to prove Lance Armstrong used performance enhancing drugs.

Lawyer Jeffrey Tillotson, who handled the case for SCA Promotions Inc., says his office will send the documents to federal prosecutors in Los Angeles who are investigating cheating in professional cycling.

The Wall Street Journal first reported the subpoena Tuesday.

The records include depositions from former Tour de France winner Greg LeMond, former Armstrong teammate Frankie Andreu and his wife, and testimony from Armstrong and his business associates.

SCA wanted to avoid paying Armstrong a US$5-million performance bonus. The case ended with SCA paying Armstrong $7.5 million.
