He touched my back and pulled my bra fasteners. What does it mean?

We were going downstairs and when we got out of the building he came closer and touched my back. We crossed the street when he was holding my back then he gently pulled the fasteners of my bra.

Does it mean anything special? Was he trying to give me a message?
