Only days after former Miami Dolphins OL Jonathan Martin was arrested and taken to a mental health facility for threatening gun violence against his former high school, another ex-college athlete is in jail.

On Feb. 23, former Arizona State DB Robbie Robinson was taken into custody for a series of tweets he sent, one of which included a threat of violence against Arizona State’s stadium.

The tweet about him trying to buy a gun is included below, containing some vulgar language at the end:

Robinson played in 10 games as a freshman for the Sun Devils in 2016. He announced that he was transferring following the season.

According to ESPN.com, Robinson is being held in the Maricopa County Jail on a $50,000 bond.
