WASHINGTON — Show me your hands, or your dance moves.

A D.C. police officer helped defuse a fight between teenagers in a Washington park by challenging one of them to a dance-off.

Seventeen-year-old Aaliyah Taylor says a woman officer arrived Monday and when she saw Taylor dancing to the popular song, “Watch Me (Whip/Nae Nae),” the officer laughed and said she had better dance moves.

What happened next was a dance-off between the officer and the girl. Onlookers recorded the dance battle on their cellphones, according to The Washington Post, which posted the video.

The officer said if she won, the teens had to leave the area.

“Instead of us fighting, she tried to turn it around and make it something fun,” Taylor said. “I never expected cops to be that cool. There are some good cops.”

The officer matched Taylor with each step. Taylor said the officer would have kept going, but after several minutes of dancing, the teen got tired, so the two hugged and everyone left.

The officer has been with the force for about three years and recently returned from a tour of duty in Iraq.
