Your fine to prove an adequate description of criminals, especially if it is coming from an official source (I.e. MPD). Even better, you could reference or cite where you have gotten your description from. What you shouldn’t do, is provide vague references to the criminals features. Why? If you provide ambiguous statements like “you guess the race” it can leave others to assume things about your intention/message.

As an example of what one could assume about your ambiguous statement earlier of the criminal: Did you intend to say, you can just assume it was a person of color? If so, obviously that’s a prejudge thing to do.

Upshot: Clear. Concise. And credibly cited criminal profiles are not a problem.
