Federal authorities have issued grand jury subpoenas to witnesses in a probe of possible fraud and doping charges against Lance Armstrong and others, the New York Times reported Tuesday.
In an article posted on its Web site, the newspaper cited several people briefed on the case who requested anonymity.
The Times did not name any person who received a subpoena, but on Wednesday the New York Daily News reported that the Trek Bicycle Company was subpoenaed.
According to the Times, the subpoenas demonstrate how seriously authorities are taking allegations made by Floyd Landis, who has said that doping was endemic in the US Postal team in the early 2000s, when he competed on it with Armstrong.
Armstrong and others accused by Landis have denied the allegations and called into question the credibility of Landis, who was stripped of his 2006 Tour de France title for doping.
