Darius McCrary My Son's Paralyzed With Fear

Darius McCrary refused to return his son to his baby mama because he claims the boy has been abused by his stepdad, but he lost the fight and the boy is hysterical with fear.

We're told everything unraveled last week at LAX, when he was putting his 7-year-old boy on a Michigan-bound plane to return to his mom.  The boy had a tantrum and cops were called.
