Warwick Police are looking for the person who caused a lockdown at the Community College of Rhode Island's Knight Campus. 

Police were called to the school on Tuesday morning after reports of a man carrying a backpack with a partially exposed firearm.  The campus was placed on lockdown and police located the backpack in a wooded area, finding it contained an airsoft gun and a pellet rifle.

Police say there was no known threat to the school or the community, and the lockdown was lifted at around 1:30 p.m.
