TMZ spoke with L.A. County District Attorney stating:

"Los Angeles County prosecutors have decided NOT to file any criminal charges against actor Pierce Brosnan, who allegedly got into a scuffle with a photographer in Malibu last month. The District Attorney's office found that there was insufficient evidence to pursue a battery charge against the former 'James Bond' actor."

Brosnan had been under investigation for allegedly sucker-punching a paparazzo at a Malibu shopping center in October.
