AUBURN HILLS, MI -- Drivers traveling along northbound I-75 Saturday night were shocked to see a pornographic film playing on one of the digital billboards, according WNEM 5.

One driver told a TV station that he nearly got into a car accident because the film was playing, and he couldn’t believe what he was seeing.

The billboard is located on northbound I-75 just before M-59. Auburn Hills police received several calls regarding the billboard and said they are working to figure out how the film ended up being played. Initial reports said the billboard was owned by Outfront Media. However, the Auburn Hills police department says the billboard is actually owned by Triple Communications, whose parent company is Triple Investment Group, which owns the Pontiac Silverdome site. Triple Communications is working with police during the investigation.
