Reports: Former Dolphins OL Martin detained after threatening post closes school

Former Miami Dolphins lineman Jonathan Martin was detained by police after a threatening social media post forced his alma mater high school to close down Friday afternoon, multiple outlets reported.

A pair of Harvard-Westlake High School campuses, in Los Angeles suburbs Studio City and Beverly Crest, were closed Friday after a threat made on social media. According to ESPN, Martin was detained because of the post.

"The individual we believe responsible for the social media post in question has been detained and our investigation is ongoing," the Los Angeles Police Department announced in a statement, ESPN reported.

ESPN then added that ABC News confirmed Martin was the person detained by police.

The threat in question, posted to an Instagram account believed to belong to Martin, read "When you're a bully victim & a coward, your options are suicide, or revenge." The post also included an image of a shotgun and shells, with four social media accounts tagged and hashtags for Harvard-Westlake and the Miami Dolphins.

Among the four names tagged were former Dolphins teammates Richie Incognito and Mike Pouncey. Incognito and Pouncey were accused by Martin of bullying following incidents in 2013. Incognito was suspended by the team for three months after Martin left the club midway through the 2013 season.

Police Sgt. Frank Albarran told the Los Angeles Daily News that the post which led to the closure included wording and imagery similar to the one on the Instagram post, though Albarran did not name the person taken into custody.

Martin, 28, attended Harvard-Westlake before going on to Stanford. The Dolphins selected Martin in the second round in 2012. After two seasons in Miami, Martin was traded by Miami to San Francisco. His one season with the 49ers, 2014, was his last in the NFL. After being waived by San Francisco in March of 2015, Martin was claimed by the Carolina Panthers. He retired four months later, citing a back injury that would have held him out of the 2015 season.
