ARLINGTON, Texas — IndyCar driver Pato O’Ward and series officials are shocked by a social media post from the Department of Homeland Security.

The post touts plans for an immigration detention center in Indiana dubbed “Speedway Slammer” and includes a car with the same number as the only Mexican driver in the series. O’Ward says a lot of people were caught off guard.

Indiana is home to Indianapolis Motor Speedway, and is where the IndyCar Series is based. IndyCar says it was unaware of the planned use of the imagery and says it preferred it not being used.
