I was accused of something I didn't do and my accuser didn't see the incident happen that I was accused of. Can I file charges for being falsely acc

I was accused of puttinga scratch on this lady's car that didn't see the scratch being put on her car in 2018 while I was working a security post and had previously asked her to move her car into a parking space because she was in a fire truck/ems truck/cop car spot that had lines going through it. It was my job to ask her to move her car. She refused with an attitude and went into the store anyway. When she came back out about 5 mins later, she accused me of putting a scratch on her car. Cops were called and I called my supervisors and reports were made. The next day, a detective called me questioning me about the incident I was accused of. The detective threatened me before getting off the phone with me. I thought nothing of it because I didn't do anything wrong. This happened somewhere around May 2018. The following year in 2019 after I had changed jobs, I was pulled over and arrested for a warrant I didn't know was out for me.
