Jacob Blake has spoken out for the first time since a police officer shot him several times in the back, as he walked away from three policemen moving to detain him on 23 August.

In a video posted on Twitter on Saturday evening by his family’s lawyer, the 29-year-old father-of-six says from his hospital bed that he is still in constant pain from the shooting:

"Every 24 hours it's pain, nothing but pain. It hurts to breathe, it hurts to sleep, it hurts to move from side-to-side, it hurts to eat".

"Stick together, make some money, make everything easier for our people out there, man, because there's so much time that's been wasted", he urged.

Blake, a black man from Kenosha, Wisconsin, was shot in the back by a white police officer after attempting to escape from three others who were trying to arrest him. As Jacob leaned into his car, having unlocked the driver-side door, officer Rusten Sheskey shot him seven times in the back.

The shooting was captured on camera by a passer-by, 22-year-old Raysean White, and it eventually sparked several nights of unrest in Kenosha, a town between Milwaukee and Chicago. The man who captured the video said he saw Blake scuffling with three officers and heard them yell "drop the knife", before the shooting could be heard. A knife was later recovered from Blake's vehicle, but it is not immediately clear if he held it during the altercation with police.

The Kenosha police union said Blake had the knife and refused orders to drop it as he fought with the officers. Police said they twice used an electroshock device to stop Blake, but it didn't help.

While an investigation into the matter is currently underway, Sheskey and his colleagues who were at the scene have been placed on administrative leave. None of them has been charged.

Blake, who had an outstanding warrant, pleaded not guilty on Friday: he appeared via video connection from his hospital bed, wearing a dress shirt and tie to respond to the judge’s questions.
