Batman Vol.1 #402
Two muggers named Roach and Spider brutalize a couple named Dick and Jane. Batman arrives and snaps both of their necks, killing them. He rides a motorcycle back to his garage, where it's revealed that this Batman is someone other than Bruce Wayne.
The real Batman responds to the Bat-Signal and swings over to GCPD Headquarters. Deputy Commissioner Barnes is waiting to arrest him for the murders, and the GCPD shoot at him as he escapes. Batman goes to visit the home of Jim Gordon, who explains that Barnes is trying to take over the department. A news report reveals that the two muggers killed were both murderers, previously released on a technicality. Batman tells Gordon to pretend to help with the manhunt so he can keep an eye on Barnes.
