Johnstown Sgt Patrick Goggin says the 12-year-old approached the stand Monday with what appeared to be a handgun in his pocket and threatened the younger boy. Goggin says the boys "got into a wrestling match over the money box" before the older boy took USD 30 and ran away.
Three other children chased the boy home and helped police track him down. That's when police determined the boy had a BB gun.
Police aren't identifying the suspect because he'll be charged in juvenile court where most cases remain confidential.
