YEADON, Pa. (CBS) – A Delaware County high school was evacuated after a bomb threat was received Friday morning.

The incident happened at Penn Wood High School’s Cypress Street campus in Yeadon.

According to a representative from the Penn Wood School District, someone called 911 and phoned in a bomb threat to the Cypress Street campus.

The school was evacuated and students were taken to a bleacher area near the school’s athletic field.

Police were called to the scene and officers used K9 dogs to search the building and its perimeter.

Nothing suspicious was discovered and the all-clear was given and the building was reopened. However, the afternoon session for 9th and 10th grade students was canceled as a precaution.

The high school is no stranger to police activity in recent weeks. The school’s Green Avenue campus, which normally housed juniors and seniors, was damaged by arson on April 18th (See Related Story). As a result of the arson, the building is not suitable for class and juniors and seniors began attending the Cypress Street campus on Monday of this week.

Police continue their investigation into Friday morning’s bomb threat.

On Friday afternoon, Congressman Brady asked that U.S. Attorney Zane Memeger launch an investigation into both incidents.

“In a letter sent today I have requested that the U.S. Attorney conduct an investigation into the break-in and arson at the Penn Wood High School in Yeadon that were preceded by multiple threats against the school. The arson, that caused considerable damage, has now been followed today by a telephoned threat to blow up the William Penn High School also in Yeadon. Any threat to blow up our children must be treated as a high level and real threat,” Congressman Brady said in a release.
