Several people are wanted on charges of reckless endangerment and making terroristic threats for causing a panic in a Walmart on Saturday by yelling “active shooter” and related warnings in the store, police said.

A witness told police that four or five men walked into the store at 100 E. Street Rd. about 1:44 p.m. and one or more of them started screaming "active shooter,” “gun,” and “get down on the ground,” prompting many shoppers to run out in a panic, according to a police statement. The men then began laughing before leaving the store, fleeing the area accompanied by a woman in a silver or light-blue Nissan Rogue with Pennsylvania license plate KCT-3096.

Authorities ask that anyone with information about the episode contact police at 215-672-1000.
