Gun recovered from Zimmerman
Police say they have recovered a handgun from George Zimmerman and another two guns from a man accused of shooting at him.
Mr Zimmerman is a former neighbourhood watch volunteer security guard from Florida who was acquitted two years ago over the death of an unarmed black teenager.
The case sparked protests and a national debate about race relations. The US justice department later announced it was not bringing a civil rights case against Mr Zimmerman.
The shooting is the latest in a series of run-ins he has had with the law, random strangers and his ex-wife.
In Lake Mary, a suburb of Orlando, police said detectives are still investigating and no charges have been filed against Mr Zimmerman or Matthew Apperson.
They were involved in a road-rage episode earlier this year but no charges were filed.
Two guns were taken from Mr Apperson's car, including a revolver that had a spent shell casing. Police say they will also execute a search warrant on Mr Zimmerman's pickup truck.
Both men had the guns legally.
Police say the shooting occurred on a busy road. Mr Zimmerman suffered minor injuries.
