A Denver police officer who earned fame as a contestant on "American Gladiator" is the focus of an internal affairs investigation that has taken her off the street, police officials confirmed Thursday.

Abbegayle M. Dorn, a seven-year-veteran of the department who most recently patrolled out of the District 3 station in southeast Denver, was moved to an "administrative assignment" on Monday while the internal affairs bureau conducts its probe, said Lt. Matt Murray, a police spokesman.

He would not comment on the nature of the investigation.

Dorn could not be reached for comment Thursday.

She and another Denver officer, Vicki Ferrari, were Gladiator contestants in 2008. Two years later, Dorn was sued federally by Rohit Mukherjee, who said she and two other officers "tortured" him while responding to complaints of loud music during a party. The lawsuit claimed Dorn took several cellphones and dunked them in a bowl of water to destroy any evidence that could be used against the officers.

Mukherjee's attorney said the suit was settled in 2011 for $30,000.
