Gloucester Township police say they are seeing an uptick in these crimes now that the weather is getting nicer.
Police are asking parents to make sure they monitor their children who have these toys. Police say if you see your child leaving the house with it, make sure you know where they're going and what they're doing.
"They're brazen, doing it driving around and startling people," said Gloucester Township Police Chief David Harkins.

Police say some teens may be doing it as part of a social media challenge, firing from a car at pedestrians. In the process, they're injuring pedestrians and animals.
"This is a dangerous practice they're doing, they can get themselves in trouble. It is a crime when you're firing it on someone who is unaware," said Harkins.
One recent incident happened at Gloucester Township Day at Veterans Park, where rowdy teens got into multiple fights.
"Some kids had fired these pellets allegedly at a pony that was giving pony rides which that could be very dangerous," said Harkins.

Police have already confiscated several guns and pellets from that day.
"You don't just get hit with one, they're stinging you with multiple because they fire very quickly out of these," said Harkins.
Locals say they're concerned the toys that could be mistaken for a real gun.

"They do have some that look realistic," said Anthony Nash, of Clementon, New Jersey.
"They better hope nobody else shoots back at them," said Robert Pease, of Clementon, New Jersey.
That's why police want teens to stop before someone gets severely injured.
"If you had a car go by and you hear this clicking and you feel this sting, you certainly could think that initial reaction of being startled, thinking you may have been shot by something, you know, even a real gun. It becomes dangerous," said Harkins.
Police say charges range from harassment, to assault to possession of a weapon. Authorities say the bottom line is if you use the toy gun as a weapon you'll get charged with it as a weapon.
