Sacramento Fire Department investigators have arrested a man in connection with a string of arson fires along Freeport Boulevard.

James C. Miller, 49, is suspected of setting six grass and debris fires between Belleau Wood Lane and Florin Road just before midnight on Saturday. Witnesses saw a man running from the fires, and investigators took him into custody.

No structures were damaged. Fire Department investigators are looking into whether Miller is responsible for other recent fires in the area.
