Cleared from a cloud of suspicion, Broncos defensive end Elvis Dumervil said he will now focus on having his best season in 2012.

Dumervil learned Tuesday that the Miami-Dade (Fla.) state attorney’s office will not file a formal charge of aggravated assault against him.

“I’m in the prime of my career and I haven’t had a chance to show it yet,” Dumervil said. “This year, all the hard work I put in with my teammates during the offseason, all the work I put in learning the (coach Jack) Del Rio package, getting my body in top condition, it will not go unnoticed. So despite all this, whatever happened, my hard work will not go unnoticed.”

One of the NFL’s top pass rushers, Dumervil was arrested on suspicion of aggravated assault with a weapon — a Class 3 felony — by Miami Beach police after a road rage incident July 14.

The state attorney’s office decided Tuesday not to formally charge Dumervil of any wrongdoing.

“I knew I didn’t do anything wrong,” Dumervil said. “It was a matter of being in the wrong place at the wrong time. I’m just ready for football.”

According to a statement from Miami-Dade state attorney James Chimura, “the victims” in this case were notified to appear for statements July 25 and Aug. 6. Additionally, “the witness and reporter failed to appear.”

“Based on the above, the State will take a no-action in the above case,” Chimura wrote in an e-mail.

“The reason they didn’t file charges wasn’t because witnesses didn’t come forward,” said Dumervil’s attorney, Harvey Steinberg. “No charges were filed because Elvis didn’t do anything wrong. And we did present taped statements from witnesses confirming that fact.”

According to the police report, an argument on a busy South Beach street resulted in Dumervil and friend Andy Auguste allegedly approaching occupants in a white Impala, raising their shirts and each displaying a gun in their waistbands.

“I never had a gun on me at all,” Dumervil said Tuesday. “I never left the area right outside my car door.”

Police arrested Dumervil and Auguste while they remained stuck in traffic, even though the 911 call by a witness from a nearby Victoria’s Secret store that brought police to the incident did not implicate Dumervil.

The 911 caller said a man had “a gun pointing to somebody.” The caller said the man was an African-American in a white car. Police later determined that the male and female occupants of the white Impala were of “white Hispanic descent” and were identified as the victims in the incident.

Later in the 911 call, the witness said the disturbance was between a male in the white Impala and a person in a silver Mercedes. Auguste was in the Mercedes. Passengers in the Land Rover that Dumervil was driving were not mentioned in the 911 call.

“We had conducted an investigation and spoken with the Victoria’s Secret employee who confirmed that Elvis had done nothing wrong,” said Steinberg, who flew to Miami to conduct his own investigation. “And the media reports and police reports had inaccurately portrayed what she had said. When we learned of that information, we were confident the authorities would not file charges.”

Perhaps now Dumervil can enter a season with no impediments for the first time since 2009, when he led the NFL in sacks with a Broncos-record 17. He had a season-ending torn pectoral muscle injury in 2010 training camp and was limited by injuries in 2011.

“It’s not what happens but how you respond to things,” Dumervil said. “The type of person I am, how I’ve conducted myself since I’ve been here — I’m just ready to continue with my life.”
