Tony Wicker

Tony Wicker was one of the GCPD cops abducted by Harley Quinn two weeks after the events at Arkham City.

History
Tony Wicker alongside several other cops, while attempting to shut down Arkham City, ended up captured by the Joker's gang led by Harley Quinn, two weeks after the Joker died from Titan-poisoning. He ended up beaten before being relocated alongside all except for one of the cops. However, his injuries left a trail that Batman eventually followed to their location, as well as to his capture.
