Nightwing # 1 - Child of Justice

Batman sent Nightwing to Bludhaven to find out why 21 members of the Angel Marin Gang got their necks broken. His first night there, he saw the False Facers attacking Freddy Minh's house (who was his first suspect). He caught up to the False Facers and was knocked into the river handcuffed to a refrigerator. He escaped. The police were not happy to have their own vigilante; Nightwing was cuffed and taken into custody when he tried to return Minh's stolen property.
