Black Lives Matter protesters in Rochester, New York, mobbed a Wegmans grocery store on Tuesday afternoon, trapping an estimated 100 customers inside.

Video shows protesters chanting “Black Lives Matter” and referring to Daniel Prude, a black man who died about week after a viral encounter with the Rochester Police Department. The state’s Democratic Attorney General announced last month that a grand jury will not seek charges against officers involved in the incident.

Before heading to the grocery store, protesters yelled, “We have a long walk today, we’re shutting s*** down,” according to 13WHAM-TV reporter Michael Schwartz.
