A number of items were at the scene, including pieces of wood, which police are determining whether they were used in the fight.

Andy, the owner of an adjacent steel business who did not want to give his last name for publication, said the fight occurred outside his premises but did not cause any damage. He said the owner of the trailer business notified him of the incident on Sunday morning.

“It’s very strange,” he said. “This shouldn’t be happening.”

Paramedics attended the scene but did not provide any medical care or transport. Police have made no arrests and investigations are ongoing.
