LUTHER, Oklahoma - The Luther Police Department is increasing its presence at Luther High School, after receiving reports of a school threat, Friday.

Authorities were notified by the FBI office in Tulsa of a threat against the school being posted to the social media app Snapchat, around 4:30 a.m.

Luther PD conducted a search of all schools and classes continued as normal, according to Luther Chief of Police David Randall. 

Investigators say they have contacted the families of two names possibly associated with the threat.

Further investigation revealed that the Snapchat account belongs to a 12-year-old girl, however the account is connected to multiple names. 

Authorities say the account has ties to a former student. They are unsure at this time if the account was hacked or duplicated.
