At about 3:00 AM on Sunday, June 26, 2016, officers assigned to District A-1 (Downtown) responded to a radio call for a person with a knife in the area of 17 Cooper Street in the North End. On arrival, officers observed the suspect, later identified as Steven Lacolla, 26, of Boston, yelling and threatening a group of people gathered in the street. The suspect was armed with two large butcher knives and wearing a bulletproof vest. When the suspect saw the officers approaching, he turned away from the crowd and began to walk towards them, still armed with both knives. Officers maintained their distance while giving numerous verbal commands to the suspect to drop the weapons. After several tense moments, the suspect placed the butcher knives on the ground and was taken into custody without further incident. The suspect will appear in Boston Municipal Court on charges of Assault by Means of a Dangerous Weapon and Wearing a Bulletproof Vest in the Commission of a Felony.
