UPDATE: One suspect arrested. Also changed some of the details in this post based on the police report.
Shortly before midnight, four men - one armed with a shotgun and one with a knife - broke into an apartment on Endicott Street near Cooper. The gunman fired his shotgun; the occupant was not hit.
Three of the men were described as black, wearing dark clothes. One was white, in his 20s, wearing a dark gray hoodie.
