Cause of loud boom unknown
Officials Monday said they were not sure what caused the loud boom and flickering lights reported around 7 p.m. at Clovis High School.
“I don’t have a clue (what caused it),” said Clovis Fire Department Lt. Ricky Mitchell, on duty at the time of the incident.
Several people exiting the high school shortly after police were dispatched to the building said the lights inside the building flickered, but they did not know the cause, and did not appear worried.
Mitchell said police officers were patrolling the area surrounding the high school, searching for downed power lines or an alternative cause of the reports.
