Offers to settle matters then and there

He looks back and forth between the two girls, a faint smirk on his face. "I think I can guess what happened here." He comments, as the thief continues to blush furiously, her hands creeping back to cover her bottom in an adorably nervous fashion. You smirk at the sight as he continues to speak. "Now, I think that petty theft isn't worth wasting the station's time, so instead of a spanking from me and a judicial punishment, you can just take it here and now." The little thief nods frantically.

"Please officer, I will take anything to avoid getting a criminal record!" She says, her eyes pleading. She moves her hands, seeming to realize how childish she is behaving, and she clasps them to her sides, grabbing the sides of her skirt. He nods, and points to the wall. " Go stand against that, hands on your head, and I am going to talk with the girl you robbed." You decide to enter the conversation.

"Hello officer, I saw the whole thing. Since it was one of the students at my university, I feel obliged to offer my services in punishing her." You say, cutting off the girl. The officer nods. "That seems fair. I was planning to go first, have the victim - what was your name, miss? - deliver her own punishment, and they can talk about what happened, and you can finish things off. It will do her some good..." There's a brief discussion of how long and how hard everything should be, with you and the officer mostly ignoring the input the girl has, with him even threatening to spank her when she complains about being interrupted.

Soon you have a punishment plan all hashed out, and you are ready to see it delivered.
