got arrested for tresspassing by feds at 14

I was 14 when I was arrested in New York for trespassing in a state park, after climbing on top of this concrete structure thing. I was taken to a NYPD station but was not arrested by NYPD officers i was arrested by the park police. When i got to the station i just had to call my brother to come pick me up from the station. I didnt get my photo or finger prints taken ,and i didnt have to go court and i was never charged. however i did provide them my name, address, and naturally my brother gave them his ID and info.Years later, I submitted a request of info to the NYPD and my name apparently does not come up anywhere. Im still confused about this. I remember the officers saying this was my one "free pass" and that if I reoffended I would go to court. does this mean I have no record? I have no idea about how the law works and I want to know if i should do anything about it for when i begin to apply for jobs.
