SACRAMENTO — Lance Armstrong's time-trial bike that disappeared from the Team Astana truck after he used it before Stage 1 of the Tour of California has been found.

Officers said a local resident brought the custom bike, worth about $10,000, to police headquarters Wednesday morning.

The Trek Livestrong 1274 was taken after Armstrong used it during Saturday's time trial. Two other bikes belonging to Armstrong's teammates were also taken, but there was no immediate word from police about whether they were still missing.

Officers wouldn't discuss how the resident came into possession of Armstrong's bicycle, citing an ongoing investigation.

More than 900 people had enlisted in a search for the bike through a Facebook group "1 Million Citizens Looking for Lance Armstrong's Stolen Bike." The search was set up by Gov. Arnold Schwarzenegger's communications office.

Sacramento Police Sgt. Norm Leong on Tuesday denied an Internet report that said the theft was caught on tape.

The fourth annual Tour of California continued Wednesday with a 115.4-mile road race from Merced to Clovis. Armstrong, a seven-time Tour de France winner, entered the day in fourth place.
