Police in Orange, County, California, arrested a dermatologist after her husband turned over videos of her allegedly poisoning him with Drano, a brand of drain cleaner.

The Irvine Police Department said Jack Chen, 53, became sick over the course of a month and began to suspect his wife Yue "Emily" Yu, 45, was responsible for his illness.

"He started to have unusual symptoms back in March and April," said Chen's attorney Steven Hittelman. "He went in to get checked by a doctor and found that he had had physical effects. He started to then connect the dots."

Chen, who began noticing a chemical taste in his lemonade, was later diagnosed with stomach ulcers, gastritis, and esophagitis.

After setting up cameras in the home, Chen, who is a radiologist, said he had three videos from July 11, July 18, and July 25 of Yue adding drain cleaner to his drinks.

"She takes up the bottle, she pours it in, puts the cap back on, and puts it back under the sink as though nothing else was happening in her day," Hittelman said.

Police claimed Chen "captured video evidence supporting his suspicion" and handed it over to law enforcement.

Yu, who is the director of dermatology with Mission Heritage Medical Group, was arrested last Thursday following a search warrant.

Chen has since filed for a restraining order against Yu for himself and their two children.

In the request for the restraining order, he accused Yu of being mentally, physically, and emotionally abusive toward him and their children.

"If our children let Emily know that they enjoyed spending time with me, or showed affection toward me, then Emily would put them in their room and yell at them until they assured her they would not show affection toward me," Chen wrote.

Chen has filed for divorce and is seeking sole custody of the children.

Yu's attorney, David Wohl, said the allegations made against Yu are "absolutely and unequivocally" false.

Wohl suggested Chen is accusing Yu of poisoning him to gain an advantage in the couple's divorce and custody battle.

"There is absolutely nothing done in those videos that were in any way illegal," Wohl said. "The videos do not depict her trying to poison her husband or harm anyone in her family."

Orange County Jail records indicate Yu posted bond on Aug. 5 and was released from custody. Charges have yet to be filed against Yu.
