A possible case of animal abuse was caught on camera. Video from animal activist group Kris Kelly Foundation shows a man yanking a dog over and over by the collar. The dog was left lying on the ground.

The Kris Kelly Foundation says this happened at a dog training business in Rahway.

Rahway police say they're aware of the video and are calling it a "possible animal cruelty" case.

“Rest assured, the mayor, the police director, and the entire Rahway Police Department take matters like this very seriously and are taking immediate steps to address the situation,” Rahway police said in a statement posted on Facebook.

Police say an investigation is underway.
