More than a year after he was arrested for beating his Pomeranian to death, a jury has found a Westbury man guilty of animal cruelty, Nassau County prosecutors said Friday.

Bing Jie Yang, 24, was arrested after bringing the 2-year-old dog in for medical treatment on April 7, 2015. Veterinarians were unable to save the dog, which had broken ribs, internal bleeding and a torn liver.

Yang, who is a Chinese national studying in the United States, was convicted Thursday of misdemeanor animal cruelty after a five-day trial. He is due back in court on Sept. 15 for sentencing and faces up to a year in prison.

Mingli Chen, a Flushing-based attorney who represented Yang, said he maintains Yang’s innocence.

“I think the jury made the wrong decision,” he said, adding that he believed holes in the police investigation led to his client’s conviction.

However, Chen said it is still undecided whether they will appeal the verdict.

Prosecutors said Yang had repeatedly struck Dan Dan after the dog had an accident in his apartment. Veterinarian hospital staff became suspicious after examining the dog’s injuries and called the Nassau County Society for the Prevention of Cruelty to Animals.

Investigators found that the dog’s injuries were consistent with blunt force trauma.

“Crimes against animals will not be tolerated and we are grateful to the Nassau County SPCA for bringing us this case,” Nassau District Attorney Madeline Singas said in a statement.
