Scott's family has already released two minutes of smartphone footage filmed by his wife.
Charlotte police will release footage of the shooting death of a black man during an encounter with officers in the state of North Carolina, Chief Kerr Putney told reporters on Saturday.
The Charlotte-Mecklenburg police chief said he will release both "the body-worn camera footage and dash-cam footage" that captured the shooting of Keith Lamont Scott, whose Tuesday death has triggered days of unrest and calls for the videos' release.
Police had previously refused to release the footage, which they said showed that the 43-year-old African American had posed a threat to officers.
"What I need is confirmation that when I release what I'm going to release, there is no adverse impact on the State Bureau of Investigation's investigation. And I have that assurance now," Putney said.
Scott was shot and killed at a Charlotte apartment complex during an encounter with police searching for another person wanted for arrest.
Police say he had a handgun. His family says he was holding a book.
Scott's family has already released two minutes of smartphone footage filmed by his wife, which does not show the shooting itself and does not conclusively answer the question of whether he was armed.
Putney said that officers saw marijuana and a weapon at which point they decided the situation posed "a safety issue for us and the public."
He added that DNA evidence would also be released.
Scott's death is the latest in a string of police-involved killings of black men that have fueled outrage across America.
