DALLAS (CBSDFW.COM) – Dallas Baptist University was evacuated due to a bomb threat against the campus, the school said. Classes were also canceled for the rest of Tuesday.

Around 4:30 p.m. the campus announced the “all clear” after all rooms and buildings were swept.

“We have received a threat against our campus and are evacuating the DBU campus IMMEDIATELY. For those who cannot evacuate the main campus, move to the Burg Center immediately,” DBU said in the early afternoon.

The school was on lockdown and no one except emergency personnel was allowed on campus during that time.
