LEXINGTON, N.C. -- Firefighters in Davidson County responded to three fires within three hours early Tuesday morning.

No injuries were reported. Davidson County EMS said fire departments have not determined whether the fires were intentional or accidental or whether they were related. The fire marshal's office is investigating.

Two of the fires happened within 15 minutes of each other in Arcadia.

The first call came in just before 1 a.m. Crews responded and found 12 bales of hay and a dumpster on fire near a business at the intersection of Friedberg Church and Old Scott Farm roads. The Arcadia Fire Department said as of 6 a.m., fire crews had cleared the scene, and the damage was limited to the contents of the dumpster and burned hay bales.

Dispatchers received a call at 1:10 a.m. about a fire on Highway 150 at Arcadia Nursery. Crews closed the road while they worked to control the flames. Angie Sweatt, the daughter of Arcadia Nursery's owner, told WFMY News 2 she believes the fires are suspicious. She explained Arcadia Nursery has been a family business for 45 years and employees always exercise safety. She said there never has been a fire at Arcadia Nursery.

At 3:36 a.m., EMS received a report of a fire in Thomasville. Upon responding, the Thomasville Fire Department found a bus on fire at the YMCA on Mendenhall Street. The bus was parked in the lot, and the fire has since been extinguished. Fire crews have cleared the scene at that location.
