Gabriel Aubry and Olivier Martinez got into a physical altercation at Halle Berry's home on Thursday, Nov. 22, Us Weekly has confirmed.

A Hollywood division watch commander for the LAPD tells Us "the investigation is ongoing" and says "the cause of the fight between the two men is unknown." However, a law enforcement sources tell TMZ the fight began when Aubry showed up with his daughter, Nahla, 4, for a custodial handoff to Berry. After Martinez (the Academy Award winner's fiance) reportedly told the model, "We have to move on," Aubry pushed the actor and threw a punch at him.

The two continued to struggle until Martinez managed to pin Aubry to the ground, according to TMZ. The site also claims Aubry sustained a broken rib, contusions on his face and a possible head injury. Martinez may have broken his hand and suffered neck injuries.

Police were called to make a citizen's arrest for battery against Aubry, 36. The watch commander tells Us that "no one has been booked yet. One man was transported with unknown injuries to a local hospital. I do not know the extent of the injuries or if he remains in the hospital."

According to Radar Online, Martinez, Aubry and Berry were cordial during a pre-holiday party Nov. 21.

Earlier this month, a judge ruled that Berry, 46, will not be able to move to France full-time with Nahla. Following their April 2010 split, the exes have been engaged in a nasty custody battle.
