UNLV says a false alert for a reported gunman on campus was accidentally triggered Wednesday afternoon as a campus police officer was testing the emergency notification system.
UNLV spokesman Tony Allen said texts and automated calls alerting 34,000 students and staff to a suspect with a firearm on campus was accidentally sent at 2:50 p.m.
An all-clear notification came four minutes later.
Allen said a campus police officer was showing another person the UNLV emergency notification system and conducting a periodic test when the gunman alert was accidentally triggered.
The campus was not evacuated and university operations were not affected.
The alert prompted Clark County fire and Las Vegas police to respond.
Las Vegas police officer Larry Hadfield said no evidence or indication of a shooter was found.
