Report: Former NFL player taken into custody after apparent threat to ex-teammates

This isn't good.

According to Matt Stone of ABC 8, former Miami Dolphins player Jonathan Martin was taken into custody on Friday after an Instagram post that featured an apparent threat to former teammates.

The post featured a picture of a gun with the hashtags "#MiamiDolphins" and "#HarvardWestlake" on it, as well as having former teammates Richie Incognito and Mike Pouncey tagged. The post was also captioned: "When you're a bully victim & a coward, your options are suicide, or revenge"

Harvard Westlake School, a private school that Martin attended before his NFL days, was closed on Friday after school officials became aware of the online post. Martin's post comes just a week after a shooting at Marjory Stoneman Douglas High School in Florida killed 17 people.

It is unclear if Martin has been charged with a crime at this point in time.

Martin was at the center of a bullying scandal that rocked the Dolphins several years ago. The scandal eventually resulted in Incognito being suspended for eight games by the NFL for his alleged involvement in the harassment of Martin.

Martin has since retired from the NFL due to injuries sustained while playing football.
