If you hear word that the Bolingbrook High School is locked down Thursday morning, well, it's just a routine search. There is no danger, said Larry Randa, director of community relations for Valley View School District.

Bolingbrook High School is conducting a soft lockdown for the purposes of a routine search of lockers by state and local law enforcement authorities, Randa said. Though not a drill, this is a routine procedure conducted at least one time annually at most high schools.
