Penn State students have a long tradition of daytime parties on the first warm Saturday of spring, but such a party last Saturday at Penn State Altoona has led to felony riot charges being filed against 12 students, after Logan Township Police claim the party got out of hand. Police estimate that between 800 to 1,000 people were partying in the parking lot of Nittany Pointe when they arrived to break it up. Angry partiers threw bottles at the police, but no charges against the bottle throwers have been filed yet. Should these people be identified, they can expect to be charged with propulsion of missile, simple assault and aggravated assault. Because a thrown bottle can be a deadly weapon, their sentences would be more severe than usual, should they be convicted.
