ORLANDO (CBSMiami/AP) — The man acquitted in the shooting death of unarmed Miami Gardens teen Trayvon Martin may be in trouble with the law again.

Police say a driver has reported that George Zimmerman threatened to kill him after a confrontation on the road.

Police are investigating two reports involving the driver and 30-year-old Zimmerman, who was acquitted in 2013 of a second-degree murder charge for shooting Martin.

Police say that on Tuesday, the man called police after a truck pulled up next to him and the driver yelled, “Why are you pointing a finger at me?”

Police spokeswoman Bianca Gillett said the man recognized the truck driver as Zimmerman. The man says Zimmerman asked, “Do you know who I am?” and threatened to kill him.

That’s when the man pulled into the nearest gas station to call Lake Mary police who later released the 911 calls from that night.

The man who identified himself as “Matt” said in the 911 call, “There was a passenger going, “Hey what’s your problem? Why are you shaking your finger?” I said, “Excuse me?…I looked over and it’s George Zimmerman who was the driver and they were threatening to kick my [expletive] and to shoot me! I said what are you going to do? Shoot me?”

The dispatcher then asks, “And you know this was George Zimmerman?” The man responds, “Oh, for a fact!”

“He then came up, in his ridgeline, this will be on camera, toward my car, almost hit my car, an aggressive move and said he was going to shoot me dead,” said Matt over the phone with a dispatcher.

“Are they still there,” asked the dispatcher. “They peeled off,” said Matt.

In the call the dispatcher asks Matt, “Just confirming this was all verbal. You didn’t see a gun or anything. This was just voiced to you?”The caller replied by saying, “That’s all verbal. He did not flash a gun.”

Two days later, the man said he saw Zimmerman in his truck outside his work. He called police again but declined to press charges. His name hasn’t been released.

Zimmerman was then stopped and questioned by police. He told them he was in the area to buy something and even said he had a receipt for the purchase and was let go.

Lake Mary police had two previous encounters with Zimmerman last year, once when his estranged wife, Shellie Zimmerman, told police he had threatened her and her father. She later declined to press charges.

In a second incident, Zimmerman was arrested and accused of domestic violence by a girlfriend, who later changed her story and dropped charges.
