The D.C. fire department is investigating a Monday night blaze that caused extensive damage to a vacant Northeast elementary school.
Firefighters responded to a call on the 1300 block of Mt. Olivet Road around 11 p.m. and found heavy fire coming from Webb Elementary School, Battalion Chief Brian Lee said.
The structural integrity of the building was damaged, so firefighters used large diameter attack lines, deck guns and ladder pipes to shoot water into the school.
Approximately 85 firefighters spent three to four hours battling the flames, Mr. Lee said.
Fire marshals are in the preliminary stages of investigating the cause.
Webb Elementary closed in 2009 and was being used as a warehouse.
