Flock cameras in Oakland have been vandalized with paint.

It’s unclear who is responsible for the vandalism. Oakland police said they are aware of the damage and are investigating.

In a statement, Flock Safety said, “When a camera is damaged, it directly impacts public safety…While Flock supports individuals making their voices heard in the democratic process, committing criminal acts should never be a part of that process.”
