UPDATE: Classes Resume At Phoenixville HS After Lockdown, Bomb Threats

PHOENIXVILLE, PA -- Phoenixville High School has been given the all clear after bomb threats led to a lockdown Thursday morning, the school district said.

A student placed a backpack on the floor of the school and claimed there was a bomb inside, according to the school.

A teacher overheard the comment and reported it immediately, at around 10 a.m.

No explosive were found in the bag. Police searched the premises thoroughly with the help of bomb-sniffing dogs before giving the all-clear.

The school was placed on lockdown and students filled into the stadium outside of the school.

The school said they would return to a normal schedule after the all-clear was given. All activities will proceed as scheduled Thursday.

"The Phoenixville Area School District thanks the all of the local and county police departments who responded and assisted clearing the building," the district said. "In addition, we thank the Phoenixville Area High School Administrators, Faculty, and Staff who were all instrumental in keeping students calm and safe during the evacuation."

The middle school was not affected by the threat, and students there continued their normal routine while the high school was evacuated.

More information will be provided as it becomes available.
