Harvard-Westlake High School filed a workplace violence prevention restraining order against former NFL offensive lineman Jonathan Martin Thursday at the Santa Monica Courthouse, according to a spokesperson for the Los Angeles County Superior Court.
Martin was detained for questioning in Los Angeles last Friday as a result of a threatening image posted on social media, but 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 was being held in a mental health facility.
It's unclear if Martin posted the image to the verified Instagram account that is believed to be his.
