The Jacksonville Sheriff's Office say they found bomb-making materials inside a home on Oakwood Drive in Arlington early Monday morning.
They were called about a fight between brothers and found the materials when they arrived at the home.
"There are just specific things that we look for -- wires, maybe some computer chips, power sources, things of that nature, and some things the suspect said to his brother," Sergeant Chris King tells our partner Action News. "It alerted patrol. They went ahead and notified us."
Police say there is no danger to the community and they do not believe it's part of a bigger plot.
The man who investigators say started the fight is in jail this morning.
