"Chicago P.D." star Josh Segarra has joined "Arrow" Season 5 in a series regular role. According to Deadline, he will play Adrian Chase, "Star City's new district attorney and an ally of Mayor Oliver Queen, who aims to clean up the streets through the legal system."

In the comics, Chase also masquerades as the Vigilante. He debuted in 1983's "New Teen Titans Annual #2," where he took up the Vigilante mantle to seek justice for his family's murder by mobsters. He is also connected to Deathstroke, who appeared as the primary antagonist of "Arrow" Season 2. It is unclear if Chase will also be Vigilante when he arrives on "Arrow" Season 5, or if he will develop into this role.

Starring Stephen Amell, Emily Bett Rickards and David Ramsey, "Arrow" will return to The CW this fall on Wednesdays at 8 pm EST.
