ALL SUMMER - homeless encampment and coordinated drug dealing on southwest corner of the green across from shakeshack. A gang has taken up under umbrellas that remain for months and use walkie talkies and bikes to run drugs through the green. I have alerted the NHPD and alderwoman to no avail. The are is a see of literal litter, trash and derelicts who have been harassing passers by and taunting them. They are vagrants who are eroding the quality of life of our city.
