At about 4:15 AM, on Sunday, March 31, 2024, officers assigned to District C-11 (Dorchester) arrested Luca Delguado Santos, 20, of Mattapan, Stephanie Ilma, 24, of Mattapan, and Miguel Martinez, 20, of Boston, on various charges. Officers responded to the area of 4 Sumner Square for a report of a loud party. Upon arrival, officers observed multiple vehicles parked on the sidewalk on both sides of the street, blocking emergency vehicle access. Officers could hear the loud music, and observed a large group of about 70 individuals. Officers advised the group to leave the area multiple times which they refused. Officers observed Santos enticing the crowd by playing music from a portable boombox. As officers approached the suspect, they advised him to turn the speaker off. At this time, Santos swung the speaker and struck a police officer in the knee. Officers grabbed the speaker from Santos, and a large crowd formed around officers. A second suspect, Ilma, became extremely aggressive towards officers and refused officers orders to step back. Officers informed Ilma she was being placed under arrest, and she began to be combative by punching multiple officers. A violent struggle ensued, and officers were safely able to place Ilma into handcuffs. During the struggle, Santos jumped on top of officers and attempted to intervene in the arrest of Ilma. Santos refused to obey officers’ orders to stop resisting, and a second struggle ensued. With the assistance of responding officers, Santos was placed into handcuffs. At this time, Martinez began to entice the crowd that was formed around the arresting officers. Officers advised the suspect to leave the area, which he refused, and was subsequently placed under arrest. After a search incident to arrest, officers recovered a taser from Ilma’s purse.
