Unlucky man, I don't know where your situated or how it works in your area. You should get the owners permission i.e. the parking lot whoever it belongs too. If there fine with you using the premise I'm pretty sure that the cops can't do anything.
Although I doubt they can charge you or fine you or whatnot for riding around there as long as your not driving on the public road.
You should talk to someone who knows the law well and see what your rights are, cause I'm pretty sure cops are more likely to approach youngsters on pocket bikes etc. as your more likely to obey without questions.
If its legal for you in your country/state to record the police then record the whole conversation with your video camera on your phone as the officer approaches you, that could also be to your benefit as they would be more cautious as to what they say or do.
