DALLAS — A police dashcam video released five months after a Texas officer shot a black man appears to show the man walking away as the officer fired, and the man’s lawyer says he was not a threat.

David Collie was shot in the back, leaving him paralyzed, lawyer Nate Washington said Wednesday. Police said at the time of the July encounter that a Fort Worth officer fired twice, striking Collie ‘‘once in the lower torso.’’

The officer and a Tarrant County sheriff’s deputy with him were off-duty at the time and working a security detail at an apartment complex, Washington said.

Police were searching for two shirtless black men who they believed had committed a robbery near a gas station, Washington said. Authorities said at the time that Collie pulled a box cutter from his pocket and pointed it at the officers.

Collie was charged with aggravated assault on a public servant but a grand jury declined to indict him.

Fort Worth police on Wednesday defended the actions of the officers, whom they have not named.
