Police in Pittsburgh are warning the area about a man who allegedly tossed a pornographic paper airplane at 2 children.

A paper airplane folded with a page from an adult magazine was launched at kids playing in their yard on Saturday, launched by a white male between ages 18 and 25. The kids showed the plane to their parents, who called police.

The kids’ ages have not been released.

“We are just trying to alert residents to someone who may be doing something suspicious around children,” a department spokeswoman told the Huffington Post.

Seriously, who does this?
