break-in(?)

While this is a majority white country, the fact of somebody being black is noticeable, so it is not necessarily racist to report what was likely the most striking feature of the intruder.

Really? Useful identifying feature, is it? Would it help catch the intruder if reported? No, is the simple answer. The OP's focus on it very possibly means he didn't pick up on genuinely useful identifying features which he would have noticed on a white intruder.
