Switchblade-wielding juvenile threatens cineplex employee in Gaithersburg

Movie theater workers have it hard enough, sweeping up spilled popcorn and mopping up sticky soda after every screening for modest pay. Monday night at Rio Lakefront in Gaithersburg, they also had to deal with a violent customer. According to Montgomery County police, a patron at the AMC DINE-IN Rio Cinemas 18 pulled out a switchblade at 9:37 PM Monday, and threatened a theater employee. The juvenile suspect apparently escaped arrest.
