University of Pittsburgh police are working with City of Pittsburgh police to determine whether some students arrested along with Group of 20 protesters were actually just innocent bystanders.

If police can determine that's the case, then criminal charges of failure to disperse will be dropped against those students.

Police arrested 110 people including students and at least two journalists during demonstrations in Schenley Plaza on Friday night.

Pitt police Chief Tim Delaney says some of those arrested were students who were just trying to get into dormitories when they were caught up in the protest. Delaney says it's unclear how many of those arrested that night were Pitt students.
