Police in riot gear cleared several large crowds gathered around Fenway Park early Monday after the Red Sox won their second World Series' title in four years. Police said they made 37 arrests, mostly for disorderly conduct. Thirteen people were arrested after they refused to leave the Kenmore Square area near Fenway Park, police said. After police told a large crowd to leave, several officers were struck by rocks and bottles. Sixteen cars in one area were vandalized. No serious injuries were reported.
