Provide what you have to the police and they may seek criminal charges. You may have a civil case but if you report/dispute the charges you should be out at most $50 by your credit card company, so your fees and time to pursue this money back is up to you.
Every legal matter is fact specific, and there are often nuances in every case. This is intended for comment only, and does not create an attorney client relationship.
If you filed a police report, they will investigate, take statements then turn over to the DA for prosecution. The DA will decide to file charges and as a part of any conviction, restitution will be ordered. Good luck.
You can't. It is a popular misconception in this country that individuals can "press" charges. Only the District Attorney (most crimes), Attorney General (some crimes) or U.S. Attorney (federal crimes) have the authority to charge an individual with a criminal offense. You can file a police report, which you say you have already done. You can also give a report to the District Attorney and urge him to prosecute. But, he does not have to do so. The D.A. has virtually unbridled authority to charge or not charge anyone with anything.
Absolutely do not "pursue" this individual. That will likely only result in charges being filed against you.
