The 58-year-old festival at California Polytechnic State University was canceled "indefinitely" today after two days of pitched battles between revelers and police led to 110 arrests.
University President Warren Baker made the announcement after a morning meeting with Mayor Ron Dunin.
On Friday and Saturday nights, party-goers hurled rocks and bottles at officers, who used tear gas and fire hoses to disperse crowds. Fourteen officers and about 50 celebrators were injured. Numerous homes and vehicles were damaged.
The Poly Royal festival originally showcased student achievements but had become increasingly rowdy over the past few years as parties and entertainment were added to the activities.
