Ex-NFL lineman Martin's high school files restraining order against him

Former NFL offensive lineman Jonathan Martin is facing a restraining order from his former high school, Harvard-Westlake School, after he posted violent images on Instagram on Feb. 23, ESPN's Kyle Bonagura reports.

Harvard-Westlake, based in Los Angeles, closed for the day in response to Martin's Instagram post, but no one was harmed.

Martin, who played in the NFL for the Miami Dolphins, San Francisco 49ers, and Carolina Panthers, posted a photo of a gun to Instagram with a caption reading "when you're a bully victim & a coward, your options are suicide, or revenge," tagging Richie Incognito and Mike Pouncey in the post.

The lineman was taken into police custody and later released.

Incognito and Pouncey were found guilty of bullying Martin during their shared tenure with the Dolphins after the league conducted an investigation into Martin's complaint.
