In the evening someone from 850 St. Marks Avenue rides his motorcyle on the sidewalk and parks it in front of 850 St. Marks Avenue apartment building. The place he parks in is not a parking space, it is a entrance to the building. He needs to be notified that he is parking there illegally. Your traffic officer (car 8334) passes by but does not give the person any warning. The place he parks in is a area where many children play. I'm afraid that some ones child may get hit.
