My question involves criminal law for the state of: Washington.

My boyfriend called the cops because he was worried I was going to hurt myself. When they got here, they asked what happened when we fought earlier and he told them I threw a satsuma at him. The cop told me I was really close to getting arrested for DV because of this. My boyfriend said he didn't feel any threat and he wasn't hurt at all. The officer said he could MAYBE arrest me but it probably wouldn't go anywhere. He ended up taking down my info and said he had to fill out a report. I asked if I was in any legal trouble or if I would be arrested and he said no. Should I be concerned about an arrest warrant? Or no, since they told me nothing would happen?
