KUSA - Officers involved in the Alex Landau incident will not face criminal charges or further disciplinary action, according to an administrative review released Friday.

Landau says he was beaten to unconsciousness by three Denver Police officers after making an illegal left turn on Jan. 15, 2009. He accused the three officers - Ricky Nixon, Randy Murr and Tiffany Middleton - of trying to cover up the incident that left him scarred and suffering from neurological damage.

"I remember getting hit in the face with a radio. I was struck repeatedly in the head with a flashlight. And the next thing I know I've got a gun against my head. The officers are talking aAlex Landau Case Narrative bout shooting me," Landau told 9NEWS in 2009.

The administrative review concurs with three previous independent reviews and the Department of Justice that there is insufficient evidence to make any criminal accusations against any officer.

"There is insufficient evidence to sustain any allegations of inappropriate force, racial slurs or deceptive conduct by Officers Ricky Nixon, Randy Murr and Tiffany Middleton for the incident with Mr. Alexander Landau," Denver Public Safety officials said in a statement. "Other than reprimands by the Chief of Police for failure to make complete reports, no disciplinary action is taken against any of the involved officers."

Landau settled with the City of Denver for $795,000.

Officer Nixon was fired in 2011 in a separate excessive-force case 2009. He was reinstated after an appeal hearing. Officer Randy Murr was also fired from the Denver Police Department for allegedly lying about his involvement in a nightclub beating in 2009. He too was reinstated back on the force after a civil service hearing cleared him.

In a statement released Friday, Landau says the city failed to deliver justice.

"Today's decision to not fire the officers that brutally assaulted me over four years ago is a clear indication that the Manger of Safety and the city of Denver are not committed to cleaning up Denver Police Department's culture of violence and deception," Landau said in a statement. "This comes just two months after a federal judge said that the city of Denver fails to punish officers for excessive force and tolerates a code of silence. This is dangerous for our community and its residents. We are renewing our call for an investigation by the United States Department of Justice on a pattern and practice of abuse by Denver law enforcement. I also call on our community to join me and my family in the call for justice."
