A group of masked people storms a McDonald’s restaurant in Lynn, Massachusetts, and attacks an employee behind the counter, police say. Video of the attack circulates online as authorities investigate the incident.

Multiple outlets report that four Massachusetts teenagers are arrested in connection with the attack. The New York Post describes the group as a “mob” that violently beats the worker, while The Oregonian emphasizes the widespread circulation of video and notes that police make the arrests after reviewing or responding to the incident.

Both accounts align on the core facts: the location is a McDonald’s in Lynn, an employee is attacked behind the counter during the incident, and four teens are taken into custody. The reporting also indicates the case draws attention after footage is shared, prompting further police action.
