Three days after a developmentally disabled man was found in a gas station with chains around his ankles, his immediate family is speaking out.

Prosecutors say Cheng Xiong was beaten with boxing gloves and sticks and chained up in the family's basement. Now his brother says the allegations against his parents are false. Phong Xiong says the truth will come out in court.

Phong Xiong says you'd find boxing gloves and sticks inside any house with children who like martial arts. He says his parents are the best, and that he hasn't heard of his brother being hurt.

He also says he doesn't know how police came up with their version of the story, and that his parents should have never been arrested.

"My mother, she cried a lot," Xiong said. "She's just looking for help and support here, and we are doing our best to help her."

Phong says his brother Cheng has run from their house about five times before, and police have always brought him back home. He says Cheng is not terrified of their parents as prosecutors said during a bond hearing on Tuesday.

Phong says his parents are good people. He says they are proud U.S. citizens who are trying to live the American dream.

"When the police told me about the allegations against my parents, I just cried," he said.

Phong said the issue of whether his brother had been kept in shackles would be clarified in court. He also said Cheng had monthly visits from a social worker and a nurse before Monday.

"We can get those records from CHP and prove that Cheng has no injury," Phong said. "He is a healthy guy."

Now Phong says the family is just getting ready to tell a judge the truth, and get things back to normal.

"We're looking forward to cooperate, to do everything we can to help Cheng."

Prosecutors haven't filed criminal charges against Phong's parents, Mai Vang Xiong and Song Xiong. They're waiting for police to finish their investigation. Phong also says he called Human Services, but wasn't allowed to speak with his brother.

He also says he hopes people follow the case with an open mind.

The Xiongs' next court appearance is scheduled for December 8. They were released on a cash bond on Tuesday.
