The Sacramento Police Department has announced that they will be formally investigating the officer who slammed a black man to the ground and beat him — after a video was released on Monday.

The man assaulted by the officer in the video is accused of jaywalking. Yes, jaywalking.

While we don't see the actions before the man, Nandi Cain Jr., and the officer have a confrontation in the street, we see the officer throwing Cain to the grown and punching him in the head.

The bystander who recorded the video is heard saying in the background, "Oh my God! Why'd you take him down like that? No! That was wrong!"

Cain was initially charged with resisting arrest, but the charges were dropped. He told KCRA, "I thought I was going to be like the next Trayvon Martin," he said. "I felt like they were going to draw a gun out and shoot me in my back or try to break my arms off or something. It was supposedly for jaywalking. And then, when they put me in handcuffs and they were driving off, I heard them (talk) about they were going to get me for resisting arrest. But as you can see on the video clearly, I didn't resist at all."

The officer involved has been placed on paid administrative leave.
