Classes were held Monday at Tooele High School, one day after a fire bomb damaged the school's administrative wing and destroyed records.

Police said the Molotov cocktail was thrown through a window into the records office Sunday, igniting a fire at 3:30 a.m.Paul F. Skyles, district assistant superintendent, said the fire destroyed the book storage room, where financial and student records were stored. Copies of the records, however, are on the district computer and in microfiche.

Skyles said a crew of teachers, custodians, maintenance people and school secretaries were assembled at 9 a.m. and worked until 6 p.m. to clean up the debris.

No arrests have been made.
