PHILADELPHIA (CBS) — Another Philadelphia elementary school has asbestos concerns, officials say. A classroom at Francis Hopkinson School in Juniata Park has been shuttered after an asbestos-containing pipe fitting was discovered in it on Thursday.

A letter sent home to parents by the School District of Philadelphia explains that an unoccupied classroom will not be used until the asbestos is remediated.
