UNLV sent out a text message to all students and employees that there was an active shooter on campus before minutes later, saying the situation was all clear.

UNLV later sent a statement on the situation saying it was testing its emergency notification system when it "advertently triggered a campus-wide message referencing an active shooter on campus. There was no campus emergency and UNLV apologizes for any inconvenience."

The original text message said, "EMERGENCY! There is a suspect with a firearm on the UNLV campus."

At 2:49 p.m., UNLV Police Services sent out a tweet saying there is a suspect with a firearm on the UNLV campus but then at 2:54 p.m., said the situation is now all clear.
