George Zimmerman is reportedly in custody following a dispute involving his wife.
Police in Lake Mary, Florida, said that Zimmerman is being held at a residence of a relative on suspicion of domestic battery of his estranged wife.
There is a gun at the home and police are investigating whether it was used.
It's unclear what caused the fight between George and Shellie Zimmerman.
He hasn't been arrested. Rather, "as of right now, he has been placed in investigative detention," Lake Mary, Fla., police spokesman Zach Hudson said.
Hudson said there were three parties involved in the domestic altercation.
The incident comes two months after Zimmerman, a volunteer neighborhood watch captain, was found not guilty of murder in the shooting death of Trayvon Martin.
Just last week, Shellie Zimmerman filed for divorce from George.
