Floors of the Student Center Building were evacuated shortly after 2 p.m. Aug. 14.
At 2:52 p.m., police gave the all-clear for people gathered outside to re-enter the building.
A Student Center worker who wished to remain nameless said a worker on the fifth floor of the building told him that there was an irate man who "seemed very dangerous."
According to WSU Police Chief Anthony Holt, the man was in the Housing Office and didn't like the answer he received from housing staff about a problem he had. He became upset, causing a worker to feel threatened by the man and called police.
The worker left the office, and when she came back, the man was no longer there.
Police detained the man at the north end of the building, Holt said. He will be released because there was no weapon found on him, and no verbal threat was made, Holt said.
"Based on that, there was no crime that he could be held on," he said.
Officers were running through the hallways telling people to leave. The order to officially evacuate the building, Holt said, was not given.
WSU Police Department officers were inside and outside the building. One officer carried club-like instruments into the building. Another officer took a crowbar from the building and put it back in her trunk.
When a call of that nature comes in, Holt said, officers are quickly dispatched and begin to look for the subject of the call.
"I'd rather have way too many than not enough," Holt said.
