Reps for Karmelo Anthony -- the high schooler accused of killing Austin Metcalf at a track meet earlier this month -- say he's been "forced to evacuate" his Texas home ... over repeated instances of harassment.
Next Generation Action Network -- which has been helping Anthony in his murder case since his April 2 arrest -- claimed Monday the 17-year-old is now in "an undisclosed location" after he and his family have been the targets of "death threats, continued harassment, and physical intimidation."
In announcing Anthony's move, NGAN officials shared some videos and pictures they say show some of the disturbances the family's had to deal with in the wake of the teen's arrest.
