Grosse Pointe Park police officially opened an internal investigation today following our report Thursday that at least once officer was capturing humiliating videos and pictures of what appears to be several black men and texting them to colleagues and family.

“On Thursday, November 14 2013, the Grosse Pointe Park Public Safety Department was contacted by an individual who said that he was in possession of video clips and a photo of African American males,” police said in press release to Huffington Post. “The video clips and photo are allegedly made by an officer of this department. The department has begun an internal investigation of this matter. The Grosse Pointe Park Public Safety Department does not tolerate unprofessional conduct by its officers when interacting with any citizen they may come in contact with.”

Police have declined to update us on the investigation, but we provided them with more images from the text messages today. We’ll be giving them additional evidence this weekend.

Most of the videos are shot from squad cars while at least one black man are told to sing or dance in humiliating ways. One of the subjects is even in the back of police cars.

We will be releasing more videos in the next several days.
