Harvard-Westlake School in Los Angeles has filed a workplace violence prevention restraining order against former NFL offensive lineman Jonathan Martin, according to multiple media reports.
The order against Martin, who graduated from the school before going to Stanford, was filed at Santa Monica Courthouse, according to a spokesperson for the Los Angeles County Superior Court.
The 28-year-old Martin was detained for questioning in Los Angeles last Friday after making a threatening post that mentioned the school on Instagram. He was released later in the day, according to a spokesman for the Los Angeles Police Department.
A law enforcement source told KABC-TV in Los Angeles that Martin is being held in a mental health facility.
Martin's post said: "When you're a bully victim & a coward, your options are suicide, or revenge." An image on the post showed a shotgun and ammunition and tagged four accounts.
In addition to Harvard-Westlake, the post tagged the accounts of Martin's former Dolphins teammates Richie Incognito and Mike Pouncey, plus James Dunleavy, who attended the private school with Martin and later played basketball at USC.
