*A new  video has surfaced revealing a key part of the April 12 arrest of Freddie Gray, whose death from injuries sustained in a police transport van sparked unrest and led to a federal investigation.

The cell phone footage is from the corner of Mount and Baker streets, where the van had made its first stop en route to the police precinct. It was shot by a bystander and posted on the Baltimore Sun’s website on Wednesday.

The video shows Gray halfway out of the van, his stomach flat on the floor and his legs hanging off the back. He does not move as four officers stand over him and place shackles around his ankles.  Also, flexi-cuffs were placed around his wrists. He was then placed back into the van, head first and still on his stomach.

Gray died on April 19 from spinal injuries suffered during his police transport. Six officers have been charged in Gray’s death, including one with a count of murder. All six were indicted this week by a grand jury, and the U.S. Justice Department is investigating the entire Baltimore Police Department for brutality and civil rights violations.

Officers arrested Gray in west Baltimore for possessing a switchblade knife. They put him in a transport van without securing him with a seat belt, Baltimore City State’s Attorney Marilyn Mosby said this month in announcing charges against the officers. The video lasts a few seconds and shows the van stopped a block away from the arrest site.

She has said that following the stop, Gray sustained a neck injury from being handcuffed, shackled and unrestrained inside the police wagon. A city surveillance camera recorded part of the scene but did not show Gray at the back of the van, the Sun reported.

Police said in a statement on Twitter that because of a technical glitch footage from the camera was never uploaded to the department’s YouTube website with other surveillance video in the case.

Police did not respond for a request for comment about the bystander’s video. A Mosby spokeswoman had no immediate comment.
