Last night from 1:30-2:30am about 6 police cars with their sirens blaring were moving about and parked at the intersection of Mellon street and Mellon Terrace. The officers walked around with big flashlights, searched, stopped traffic. Does anybody know what went on? There was loud talking afterwards, but living on the 5th floor, I could not figure out what happened. I am just curious what's going on in my neighborhood that requires such a police force. Edith
