NEW YORK -- A report says disgraced cyclist Floyd Landis has collected audio and video recordings for federal officials investigating doping in cycling.
The New York Daily News citing anonymous sources Sunday said Landis wore a concealed recorder and video camera during a meeting last spring with designer and cycling team owner Michael Ball.
The sources said the recordings helped Food and Drug Administration agent Jeff Novitzky obtain a search warrant for Ball's apartment.
Landis and several members of Ball's Rock Racing team were teammates with seven-time Tour de France champion Lance Armstrong.
Landis has accused Armstrong and members of the former U.S. Postal team of systematic doping. Landis was stripped of his 2006 Tour de France title for doping.
