An arson fire gutted a vacant Fort Dodge house early Saturday morning.

The fire at 702 N. 16th St. was reported at 3:19 a.m.

No one was injured.

Residents of the house next door had to be evacuated because the houses are so close together. Firefighters prevented the blaze from spreading to the house next door.

According to Fire Department reports, firefighters found flames throughout the first and second floors of the house when they arrived.

The flames burned a hole through the floor on the second floor and spread to the attic and roof.

The blaze caused major damage to all levels of the house, according to Fire Department reports.

The house was determined to be vacant and had no utilities connected.

The cause of the fire has been determined to be arson, the Fire Department reported.

Several off-duty firefighters were called back to work to help at the scene and to respond to any other emergencies that occurred in the city.

Fort Dodge police responded along with firefighters.

According to online records of the Webster County Assessor’s Office, the house is owned by Anwar Zeeshan, of Fort Dodge. It was built in 1912, according to those records.
