VANCOUVER, Washington (AP) — Police have arrested two 18-year-old U.S. men accused of pretending to attack each other with an ax and using the ax to threaten passers-by while videotaping their reactions.

Police spokeswoman Kim Kapp says officers responded Wednesday after receiving a report that a man in motorcycle gear wielded an ax at a couple after attacking someone with the weapon. A similar report had come in the night before

The suspects allegedly told investigators they were "pranking" people with what police describe as a realistic-looking fake ax.

Pavel Krivov and Petru Tomcac were arrested for assault. It wasn't immediately known if either man had an attorney.
