Police returned to the scene Sunday of an alleged underage drinking party that turned violent in West Harrison to collect evidence.

Police say they arrived at the upscale house on Old Lake Street Saturday night after the party spilled into the road. One person allegedly stabbed someone and anther person was wielding a baseball bat. Officers arrested four people. A neighbor says the party was for a 20-year-old woman who lives at the house and the fight broke out after someone showed up uninvited. The neighbor says the uninvited guest was attacked.

Police are saying very little about the case and the house's owners asked news crews to get away from their property.
