Matt Barnes: No Criminal Charges for Fisher Incident ... Cops Say

Matt Barnes will NOT be charged with a crime for allegedly attacking Derek Fisher over the weekend ... the Redondo Beach Police Department tells TMZ Sports.

Cops tell us they did respond to an incident and a police report was filed regarding the altercation -- but officers say the case "was reviewed and there is no basis for criminal charges."

As we previously reported, a witness at the home says Barnes struck Fisher in the face and a fight ensued. However, the NY Post is reporting that Fisher did not want to pursue charges against Barnes.
