Three weeks after former NFL offensive lineman Jonathan Martin used Instagram to share a photograph of a gun and ammunition with a ominous message, he has been charged by the Los Angeles County District Attorney with four counts of making criminal threats and one count of possessing a loaded firearm, as reported by TMZ.

Martin, who has not played in the NFL since 2014, was taken into custody soon after making the post.

The photo tagged two of Martin’s former Miami Dolphins teammates: Richie Incognito, who bullied Martin during the 2013 season, and Mike Pouncey. He also referenced his high school, Harvard-Westlake in Los Angeles, which prompted the school to close for the day.
