An overnight fire caused an estimated $50,000 in damage to a Coralville business.

According to a news release, the Coralville Fire Department was called to Theisen’s, 100 Westcor Dr., around 3:40 a.m. Wednesday. The fire department credits the store’s sprinkler system for suppressing the fire before crews arrived.

The business sustained a small amount of fire damage, as well as light smoke and water damage.

Firefighters remained on scene until 6 a.m. to help with water removal so the business could open on time, the fire department said.

The cause of the fire is under investigation, but is believed to be accidental.
