To start this sidequest, talk with Tim Carella in your office. He will point you to Tindall's apartment.

You can enter the apartment building by climbing a ladder and jumping from an adjacent building, or by using the front gate code 0002.

During the conversation with Tindall, choose Activate Pheromones (requires the Social Enhancer augmentation) -> Appease to get the footage right away, or Accept his offer and go beat up P-Gee and Bee-K.
