A Baltimore police officer has been indicted on criminal charges after a body camera video taken a year ago appeared to show him staging the discovery of a bag of illicit drugs near an arrest scene.

The video ignited outrage in July when it was released by Maryland’s Office of the Public Defender. It was recorded on Jan. 24, 2017, and seems to show the officer, Richard A. Pinheiro Jr., placing a bag of white capsules inside a can in an alley. The officer can then be seen walking back to the street, at which point he appears to switch on his body camera and announce that he is going to search the alley.

The video shows him returning to the alley to find the bag he had just placed there.

The body cameras used by the Baltimore Police Department retain visual recordings beginning 30 seconds before the cameras are manually switched on.
