Potential bomb threat causes scare at Frederick County school

BALTIMORE -- A potential bomb threat was the source of a brief scare Thursday morning at a Frederick County high school.

Students and staff at Oakdale High School in Ijamsville were ordered to shelter in place after deputies learned of the threat about 7:15 a.m., the Frederick County Sheriff's Office said. 

A search of the school campus found no sign of a credible threat, deputies said, and normal operations resumed.
