A potential threat at a student housing building at IPFW yesterday afternoon caused some tense moments, and forced students outside. It happed just after two; students were told to get out because of a potential threat. About 15 minutes later, they were told it was all clear and they could go about their lives. What was wrong? IPFW is not saying at this point. Their facebook page shows a post that IPFW police removed the potential threat and everything is okay.
