Officers from the Grand Haven Department of Public Safety responded to a fire at Keys Driving School, 800 Washington Ave., at approximately 2 a.m.
They found and quickly extinguished a small fire on the west side of the building exterior, said GHDPS Director Jeff Hawke.
While searching for the suspect, officers found a second fire under a vehicle behind a residence in the neighborhood.
"Based on evidence, both fires are arson," Hawke said.
Police located and arrested the suspect.
Possible charges are being reviewed by the Ottawa County Prosecutor's Office.
Damage to the building is estimated in the hundreds of dollars, Hawke said.
