PHILADELPHIA (WPVI) --Philadelphia police say they have identified a 13-year-old girl who made so-called "clown threats" toward local schools.
According to investigators, the girl told them this was a "prank" committed with a friend at her school, and she never had any intent to harm anyone.
"If she was old enough to make the prank, she should pay for what she did. She should be punished," said Yvette Malave of North Philadelphia.
The case is being forwarded to the District Attorney's Office, police say, as the investigation continues.
Police in Washington Township, New Jersey, have arrested two teens believed to be behind threats in two separate incidents.
George Tzanis knows firsthand the terror recent clown threats have caused.
His daughter attends one of the schools that were targeted.
"My daughter and I last night we were talking about it, and she's a little bit scared," said Tzanis of Center City.
Disturbing pictures like this one were posted to Instagram.
The caption reads, "hello we are in the philadelphia area today."
The user then issued a chilling warning that kids will be kidnapped at 5 p.m.
"I really think people should take it seriously, but some other people think it's a joke, but you don't know it's a joke," said Jackie Zou of Mount Airy.
Frank Farley, a psychology professor at Temple University, says a new line has been drawn when it comes to what's considered an innocent prank.
"I don't think pranks that threaten lives are innocent anymore. This nation in 9/11 was invaded from the outside, and we've had terrorist incidents since then," said Frank Farley Ph.D., Temple University.
He adds that it's no surprise clowns are being use to scare people.
Studies have shown that they are considered the creepiest profession. But history also plays a part.
"Now a 13-year-old probably doesn't know anything about John Wayne Gacy, but most parents should know about John Wayne Gacy, who was this lovable clown in Chicago who everyone wanted this John Wayne Gacy clown to come to their children's party and so on, and he was systematically killing young boys," said Farley.
Anyone with information surrounding these posts should contact the Philadelphia Police Department at 215-686-TIPS (8477).
Last week, the Toms River Police Department said security is being stepped up at schools in their area due to reports of clown sightings.
The department offered some background into the clown sightings.
As some of you may be aware there is a story circulating around the nation regarding "creepy clown sightings." The initial reports seem to stem from an organized movie promotion and have now morphed into copycat reports throughout New Jersey. The recent social media posts and threats to schools seem to originate from outside of New Jersey. Facebook shares and retweets have brought these concerns to New Jersey.
