Sgt. Ronald Crump, 39, was moved from the Media Relations Section to the 911 division in 2009, a post he says comes with less opportunity for promotions and pay raises.
Crump, a 16-year veteran of the force, claimed Romero mistreated him because of his sexual orientation.
In one instance, according to Crump, Romero told him, "I was a religion major at Liberty University. Jerry Falwell would roll over in his grave if he knew I had hired you."
The district attorney's office maintained that Crump's transfer had nothing to do with his sexual orientation, and did not diminish his chances for advancement.
It said Crump currently earns about $110,000 annually.
Crump currently works as an assistant in charge of a Skid Row task force.
