This is the second time I have complained about this problem. There is an abandoned AT& T substation on the side of our of our building on King Street just off of Dennison , that is occupied by a very aggressive homeless person. I would take a picture but decided it was not safe as this person has aggressively confronted several of our employees. We have called at&t to ask them to either board it up or remove it but they have done nothing! This is causing a big problem for our company because of the mess he is creating but also because of the shady activity of this individual! Also this is all within clear view of the Beacon School Please help! We don't know where else to turn!
