Malfunctioning sprinkler system leads to half day at Wilmington school

WILMINGTON, Del. (WPVI) -- Students at one Wilmington high school got an unexpected half day, thanks to a malfunctioning sprinkler system.

Action News was outside the Delaware Met School on French Street as students waited to be dismissed early.

Fire officials say the sprinklers starting going off on the second floor just before noon Friday.

When they couldn't get the water to stop, the school was evacuated and the system was shut down.

Investigators are still trying to figure out why the sprinklers went haywire and how much damage was done.
