AUBURN HILLS, MI - Two hoodie-wearing suspect scaled a 6-foot fence and forced their way into a building housing computer equipment in order to run a pornographic video on a digital billboard along I-75 late Saturday night, police said.

New details have been released in the investigation by the Auburn Hills Police Department as to how the suspects gained access to the small building underneath the billboard, which holds the equipment used to run the billboard’s advertising.

“The suspects were captured on video inside the building, where they were able to access a computer and play the pornographic video on the billboard,” Lt. Ryan Gagnon said in a press release.

The two suspects got into the building at 10:49 p.m. Saturday, police said, noting the date shown on the video image is not correct. They were inside for about 15 minutes.

Because the security video camera has a night-vision component, police said it’s not known what color clothing the suspects had on.

A short time after the suspects entered the building, Auburn Hills police began to receive calls from motorists saying the billboard on the east side of I-75, south of M-59, was showing pornographic images on both its north and south sides. Officers arrived to find the video still playing, and reached out to the billboard company’s emergency contact to shut down the board.

“We believe that the video may have been playing for at least 15 to 20 minutes before it was turned off,” police said.

The sign is owned by Triple Communications, which is part of the Triple Investment Group, which owns the Pontiac Silverdome property. Company officials have been cooperating with police.

Investigators are asking for the public’s help in finding the suspects. It’s against a local law to disseminate or promote pornographic materials, and the suspects also face possible felony burglary charges, police said.

“We are requesting the public’s assistance in trying to identify the suspects responsible for this crime. If you have any information related to this case, we ask that you please contact the Auburn Hills Police Department at 248-364-9460.”
