Authorities are investigating two suspected arson fires at two apartment buildings.

One of of the fires was Monday, and the other was Wednesday. No injuries were reported.

Salina Fire Department investigator Troy Long says it appears an accelerant was used to set both fires. Samples have been sent to the Kansas Bureau of Investigation laboratory for analysis.

The first fire caused about $3,000 in structural damage. The second fire damaged the carpet on the stairway landing.
