(Portland, OR) -- Police in Eugene responded to what was described as an unruly gathering at a house that led to dozens of people either being ticketed or arrested this weekend. Police say there were about 100 people on the scene on Hilyard Street at the time they arrived Saturday following calls of a disturbance. Most of the tickets were for noise violations and open containers. It's the third time in recent weeks that Eugene police have responded to an unruly gathering.
