A doctor allegedly caught his wife trying to poison his drinks with household chemicals on secret cameras.
Dr Jack Chen, 53 and a radiologist from California, US is now seeking custody of his kids and a restraining order against wife Yue 'Emily' Yu, 45.
He is also seeking a divorce from his wife of 10 years, who he accuses of abusing him and their children.

In court documents filed on Friday (August 5) and obtained by NBCLA, Chen alleges that Yu began adding drain cleaner Drano to his drinks in March and April this year.
He claims he noticed a "chemical taste" in his lemonade and went to see a doctor who diagnosed him with stomach ulcers, gastritis and esophagitis.
After that he put cameras in the kitchen of the home he shares with his wife and their two children.
The filing alleges that the cameras caught Yu adding the chemical to his drinks on three occasions.
Screenshots from the videos were included in the filing, one showing a woman pouring from what seems to be a large red plastic bottle.
Yu was arrested on Thursday (August 4) after Chen reported the matter to the police.
Police confirmed she was "arrested for poisoning her husband" after being interviewed by detectives.
The accusations against Yu were two-fold, with he filing alleging she also abused both Chen and their kids, a boy aged 7 and a girl aged 8.
According to the New York Post, Chen wrote in the document: "When Emily gets frustrated and yells at the children, she’ll commonly use a Chinese phrase that translates to ‘go die!’
"She also says to the children, ‘your head has a problem, ‘your head is sick, ‘go f**k yourself,’ ‘f**king idiot,’ ‘stupid a**hole,’ and ‘get the f**k out of my way’."
Yu's mother, Yuqin 'Amy' Gu, was also allegedly involved in the abuse.
"As early as two-years-old Emily and Amy were verbally and then physically abusive to [our son and daughter] which intensified as they grew older," he said.
"They are both verbally and physically abusive to me."

Other alleged abuses include Yu waking the kids up if they went to bed without her permission and her isolating them from other children at school.
In a statement provided to the OC Register, Yu's attorney David Wohl said Yu: "Vehemently and unequivocally denies ever attempting to poison her husband or anyone else. As a well-respected physician her goal as always been to help people and never to harm them.
"We are very concerned that these defamatory, false allegations have been made by [her husband] in an attempt to gain an advantage in the divorce and custody case he filed against Ms. Yu, a day after she was arrested."
