Fayetteville, N.C. — Investigators said fires that hit three houses on the same street in Fayetteville were intentionally set.

Calls about the fires at three houses on Rivercliff Road came in around 2:52 a.m. Saturday. Thirteen fire crews labored until at least 5 a.m. to get the fires under control.

Five police officers also responded. No injuries were reported, but the houses were destroyed by the flames.

All three two-story houses were brand new, unoccupied and owned by the same person, investigators said. Two of the houses were beside each other, and the third was six houses down.

Investigators have not yet released the cause of the fires, but said the blazes were suspicious and intentionally set.
