Pittsburgh, Pennsylvania (AP) A crowd of about 30 people gathered Sunday outside a popular Greek restaurant in the small Pittsburgh suburb of West Chester, chanting and banging pots and pans and banging on a police car, local media reported.
Police responded and used pepper spray to disperse the crowd.
The incident occurred less than a week after a small crowd in the area of the restaurant was met with pepper spray by officers who were trying to disperse a small group of demonstrators who had blocked traffic, local reports said.
Several police officers were hurt during the clashes, the Pittsburgh Post-Gazette reported.
The protesters had been blocking traffic on I-75, an expressway through Pittsburgh’s downtown, local news outlets said.
The protests come after protests over the weekend in cities across the country and in Washington, D.C.
Protesters also staged a rally in Washington this week, and hundreds more in New York and Philadelphia have taken to the streets in the past two days.
The unrest began with the death of a 32-year-old black man in North Charleston, South Carolina, on Saturday, and spread to other parts of the country on Sunday, when police fired pepper spray and tear gas at crowds.
