Kevin Alejandro has joined Fox's "Lucifer" series as Dan, a LAPD homicide detective who is suspicious of Lucifer's relationship with his wife and his daughter. Deadline reports that Alejandro will take over the series regular role from Nicholas Gonzalez, who played Dan in the pilot.

Written by Tom Kapinos ("Californication") and directed by Len Wiseman ("Underworld"), "Lucifer" stars Tom Ellis ("Once Upon a Time," "Doctor Who") as the Lord of Hell who, bored and unhappy, resigns his throne and abandons his kingdom for Los Angeles. There, he gets his kicks helping the police punish criminals.

Alejandro's past credits include A&E's "The Returned," "True Blood," "Southland" and "Golden Boy."

The project hails from Warner Bros. Television, DC Entertainment and Jerry Bruckheimer Productions. Kapinos and Wiseman will executive produce alongside Bruckheimer, Jonathan Littman and Ildy Modrovich. While Kapinos developed the project, based on the Vertigo series written by Mike Carey and illustrated by Peter Gross, Ryan Kelly and Dean Ormston, "White Collar" and "Almost Human" Co-Executive Producer Joe Henderson will serve as showrunner for the series.

"Lucifer" will debut on Fox in 2016.
