RENO " Reno firefighters are investigating two more arson brushfires in a string of suspicious fires that began earlier this month.
Two small fires were reported Wednesday evening off U.S. 395 south of Reno-Tahoe International Airport. Fire spokesman Joe Durousseau says the fires were quickly doused and called the causes suspicious.
Fire officials have been investigating a series of arsons within nine days at Rancho San Rafael Regional Park and near the University of Nevada, Reno.
No one has been injured by the fires and no structures have been damaged.
