Sickening video has emerged of yet another police officer violently slamming a handcuffed suspect face-first into the ground.

The footage shows Colorado Springs officer Tyler Walker ramming 18-year-old Alexis Acker into the concrete floor while the girl was already restrained.

The police reports, claim that Walker "escorted her to the floor," or that he "rolled her to the floor."

Indeed, the officer "escorted" Acker to the floor with such force that her front teeth were smashed in and permanent injuries were caused, including trauma to the face, head, teeth and jaw; migraine headaches, concussion, closed head injuries, memory and cognitive function problems, as well as post traumatic stress disorder.

The incident occurred in late 2013. The video has just been released as part of a $500,000 brutality lawsuit against the CSPD.
