(KLFY / WGNO)— Six Louisiana colleges and one Texas college faced evacuations on Wednesday after bomb threats were called in, though all cases have ended so far with officials finding no evidence of explosives.

The following institutions were targeted by threats:

Most of the schools faced their bomb threats at around the same time, about 10:45 Wednesday morning, based on texts, social media, and email alerts sent by each institution. It remains unclear if the three simultaneous bomb threats were related, though officials in each case said they are working to determine where the threats originated.

According to Louisiana law, any person found guilty of calling in a bomb threat to a school or firearm-free zone faces up to 20 years in prison with hard labor.

UL sent out an emergency notification to students at around 11:35 a.m. Wednesday morning. The bomb threat call originated via 911.
