An apparent computer glitch is believed to be the cause of an emergency siren going off in Clinton just after 8 Monday morning.
There are 27 sirens, across Vermillion County.
The malfunctioning device was located just off of South Main Street, not far from Vermillion Convalescent Center.
It appears that a faulty key or other electronic part of the siren malfunctioned.
Officials say that they cannot detect a faulty device, of if you hear a siren going off on a bright and sunny day you should contact police.
