The wife of Miami Dolphins CB Brent Grimes says her September arrest was an act of revenge ... claiming she was set up and assaulted by dirty cops as retaliation for supporting the "Black Lives Matter" movement.
Miko Grimes made an appearance on the "Tax Season" podcast and opened up about the incident that went down outside Sun Life Stadium ... in which cops have said she flipped out and headbutted an officer when asked to leave a restricted area.
Miko tells a different story ... saying she was ambushed and "choked slammed" by law enforcement who warned her to "stop talking that sh*t on Twitter about Black Lives Matter."
Weird theory considering the cop who was making the arrest is black.
Check out the audio ... it's pretty explosive.
