The secondary campus at the Seneca Valley School district is under lockdown this morning, and several police officers and firefighters are there.

Two school busses are blocking Seneca School Road near the entrance to the campus. A police officer at the scene said Seneca Valley Intermediate High School is under lockdown.

However, all vehicles heading to the campus, which also includes the district's middle and high schools, are being stopped by police before being allowed to proceed.

Neither police nor school officials were available for comment this morning, but an officer at the scene said district officials would make a statement later.
