ORLANDO, Fla. (AP) -- A Florida man charged with shooting at George Zimmerman last week had "a fixation" on the former neighborhood watch leader and had recently been admitted to a mental institution, according to a police report made public Tuesday.

The Lake Mary Police Department report said that 36-year-old Matthew Apperson had shown signs of paranoia, anxiety and bipolar disorder. Apperson's attorney, Mark NeJame, didn't immediately respond to an email seeking comment.

Zimmerman told officers he had been driving in the Orlando suburb of Lake Mary when Apperson got behind his truck and yelled, "You remember me you fat mother f-----?" according to the report.

Apperson then yelled at Zimmerman, "You owe me your life. The only reason I didn't press charges on you is because I wanted to kill you myself," Zimmerman told detectives, according to the report.

Zimmerman and Apperson had a previous encounter last September, when Apperson alleged that Zimmerman had threatened him. No charges were filed.

In the most recent incident, Zimmerman told officers he laughed and called Apperson a clown, and Apperson fired a gun at his car a short time later, leaving a bullet hole in his passenger-side window. Zimmerman suffered minor injuries.

Apperson was charged last Friday with aggravated assault with a deadly weapon, aggravated battery with a deadly weapon and firing a missile into an occupied conveyance. He was released over the weekend on $35,000 bond.

Zimmerman was acquitted of any crime two years ago for fatality shooting unarmed teen Trayvon Martin.
