A North Penn High School student has been arrested for allegedly setting a fire Tuesday inside the Montgomery County high school, forcing the evacuation of the entire building.
The unidentified suspect is being held at a county juvenile detention center, the school district said in a statement on its website Friday.
No one was hurt when fire broke out in the band storage area and some first-floor classrooms. But smoke spread quickly through most of the Lansdale school, forcing 3,000 students and all staff to flee.

While firefighters were able to contain the blaze to one section of the school, the district said the cost of the damage has yet to be assessed.
“It is very concerning that one of our students is involved and it is clear that like anywhere in society, we are not immune to the potential of such acts," North Penn Superintendent Curtis R. Dietrich said in the statement.
The fire began at North Penn High School on Valley Forge Road about 11:45 a.m.
