Police have issued an all-clear at Booker T. Washington High School.
The school held students at the field house while law enforcement investigated a bomb threat.
TPS spokesperson Chris Payne says the school learned of a threat on Twitter Thursday evening. Friday morning, school administrators had all students report to the field house while the TPS Police and Tulsa Police departments conduct a sweep of the high school.
The sweep turned up nothing so administrators sent students to class.
