Harvard-Westlake School has filed for a restraining order against Jonathan Martin following his threats made last week, according to a report.

TMZ Sports reported on Thursday that the Los Angeles school filed for a restraining order against Martin. Martin posted a photo on his Instagram account last Thursday that showed a shotgun and several bullets around it. In his post, which came a little over a week after a school shooting in Parkland, Fla., Martin mentioned four people, including two former Miami Dolphins teammates. The post also mentioned Harvard-Westlake School, which was Martin’s high school.
