June 4 (UPI) -- Protesters and police clashed again at Delaney Hall Wednesday night after the city of Newark lifted a 9 p.m. curfew, resulting in two arrests.

People blocked vehicles and chanted "shame on you" after they showed up wearing helmets and gas masks, CBS News reported. They blocked traffic with bicycles and banged on the hood of a car. Police arrested two people.

Demonstrators left a designated protest area that was designed to allow the flow of traffic on the road. But protesters moved to the Delaney Hall entrance. When a vehicle approached the gate, protesters began banging on it, and Newark police helped the vehicle through the gate, NJ.com reported.

"All of a sudden the police were just pushing everyone back," Emily Phillips, a protester at the scene, told NJ. "We started yelling at some ICE vehicles or GEO Group vehicles, and from there the police got pretty aggressive pushing us back."
