MANHATTAN, Kan. (AP) — Manhattan authorities are working to determine if four arsons that occurred in one day are related.

Manhattan fire officials say the four arsons were all reported early Monday, causing a combined loss of more than $22,000.

The fires were reported at an unoccupied apartment and in three vehicles. One vehicle was destroyed, and the two others were damaged.

The fire at the apartment caused minor damage after it was extinguished by a neighbor.

No one has been arrested. There were no injuries.
