Matthew Apperson, accused of firing a gun at George Zimmerman earlier this week, was arrested on Friday night, WFTV reports. On Monday, Apperson’s lawyer said that he had acted in self-defense.

WFTV reports that Apperson has been charged with one count of aggravated assault with a deadly weapon, one count of aggravated battery with a deadly weapon, and one count of firing a deadly missile into an occupied conveyance. Apperson turned himself in to police on Friday night.

The men had met before, when they had a violent confrontation in September, police said. Apperson did not press charges at the time. During Monday’s incident, WFTV reports that Apperson allegedly told Zimmerman, “You owe me your life. The only reason I didn’t press charges on you is because I wanted to kill you myself.”

Police recovered two handguns from Apperson’s vehicle and one gun from Zimmerman’s. Both men had permits for their weapons.
