GRAND FORKS, ND (WDAZ-TV) -- Not a good idea.
University of North Dakota Police tweeted this video, giving students a tip that having people record you commit a crime isn't smart.
UND PD says the incident happened last night in a residence hall, and this Snapchat video makes finding the person behind the smashed glass that much easier.
Sargeant Danny Weigel, UND PD, "I think it makes it a little bit easier because we are able to use those same resources that they posted it on to help identify them as well."
Police are still searching for the vandals.
If you know who this person is, contact UND PD.
