The Federal Bureau of Investigation (F.B.I.) raided the 100,000-square-foot building that houses Rahal Letterman Lanigan Racing’s IndyCar and IMSA shop in Zionsville, Indiana, on September 18, according to multiple media reports.

Rahal Letterman Lanigan Racing is co-owned by former Indianapolis 500 winner Bobby Rahal, Indiana native and former late night TV talk show host David Letterman, and businessman Mike Lanigan. Rahal Letterman Lanigan Racing fields teams in the IndyCar and IMSA automobile racing series. Bobby Rahal’s son Graham drives for the team and also owns and operates the Rahal Ducati Moto team in the MotoAmerica series.

According to Rahal Ducati Moto spokesperson Britni Stewart, “We do not operate out of that building nor do we have any affiliation with RLL. We are owned and operated separately.”

The F.B.I. has not provided media outlets with the reason for the raid, but Racer.com reports that it may be linked to alleged theft of intellectual property from a rival team.
