TMZ has learned San Diego Chargers star Antonio Cromartie is being investigated for assault with a deadly weapon over a bruising incident in a San Diego bar last night.
According to law enforcement sources, Cromartie — a Pro-Bowl defensive back — was out celebrating the Chargers win at a local San Diego bar when somebody threw a champagne bottle which hit a bystander in the head.
Witnesses claim there was champagne being sprayed back and forth between Cromartie’s party and other bar patrons — until the mood changed and someone threw a bottle.
We’re told the bystander had a cut on his head — but no ambulance was called to the scene.
Law enforcement sources tell us 25-year-old Cromartie was identified as the bottle-thrower by at least one person — but there are conflicting stories from other witnesses.
