DETROIT (WXYZ) - Take a good look at the video in this story.
It shows two guys painting graffiti on a building on Detroit's near west side. They also match the description of some vandals who assaulted a downtown businessman when he caught them in the act this week .
The guys knew they were on surveillance video, because they hit one of the cameras with a brick, knocking it off the building and then running off.
If you know who they are, call Detroit Police. They have an open investigation into both cases.
