Halle Berry's ex was arrested after allegedly attacking her fiance Olivier Martinez.
The model - who is the father of Halle Berry's four-year-old daughter Nahla - reportedly attacked the actress' French fiance Olivier on Thursday morning (22.11.12) when he was dropping the tot back at Halle's house but came off worse in the fight.
Gabriel was taken to hospital for his injuries and charged with battery, while Olivier did not need extensive medical attention for his own wounds but wants to press charges.
A source told gossip website TMZ: ''Gabriel went nuts,'' in front of Halle and other witnesses.
The fight comes after Halle, 46, recently had her bid to move Nahla to France with her and Olivier, denied by a judge.
Gabriel, a Canadian model who lives and works in Los Angeles, had petitioned the court to stop Halle's plans as it would give him limited access to his daughter, while the 'Cloud Atlas' actress argued the privacy laws are stronger in France and would keep Nahla safe from the paparazzi.
Halle - who split with Gabriel in 2010- and Olivier, had put their wedding plans on hold while the actress focused on her custody battle.
