George Zimmerman was injured in a shooting incident on Monday in Florida, police said.
The shooting in Lake Mary involved Zimmerman and a man identified as Matthew Apperson, police spokeswoman Bianca Gillett said. Zimmerman did not fire any shots, according to police.
Neither man has been arrested, and investigators are working to determine whether charges will be brought, Gillett said.
Investigators are waiting to speak with both men, who sustained "minor injuries" and have been released from the hospital, Gillett said less than four hours after the shooting.
Police Chief Steve Bracknell told NBC affiliate WESH that the shooting may have been related to an "ongoing dispute."
In September 2014, Apperson accused Zimmerman of saying "he was going to shoot me dead," during a road rage incident, according to the Orlando Sentinel. Apperson did not press charges, the Sentinel reported at the time.
WESH, citing its own helicopter video, said that there was a bullet hole in a vehicle that Zimmerman had been in on Monday.
In 2013, Zimmerman was acquitted of second-degree murder by a Florida jury in the shooting death of Trayvon Martin, an unarmed teenager. The Justice Department closed its investigation into the killing earlier this year and declined to bring civil rights charges.
Zimmerman was arrested in January after police said he threw a wine bottle at his girlfriend. Prosecutors declined to bring charges after the woman recanted her statement.
Zimmerman filed a defamation suit against NBC News in 2012. A judge dismissed that claim last year, and Zimmerman has appealed.
