(AP) — Firefighters have been called to a fire at the same vacant house in Kansas City, Kan., three days in a row. No injuries have been reported.

Fire officials say all three fires are believed to be arson.

The latest fire at the single-story house was reported early Wednesday. Deputy Chief Kevin Shirley says the house already had caught fire twice earlier this week. The first fire was discovered Monday night in the back of the house. The second fire was early Tuesday.

Shirley says the fires appear to be intentional. Authorities are asking anyone with information about who might be setting the fires to call the TIPS Hotline at 816-474-TIPS (474-8477).
