Clark County District Judge Stefany Miley, 47, was arrested on Saturday in Las Vegas

A judge in Las Vegas has been charged with domestic battery for allegedly punching her 18-year-old son in the mouth.

Clark County District Judge Stefany Miley, 47, was arrested on Saturday evening after the incident, which occurred at about 6.45pm in a residential area near downtown Summerlin, a suburb of Las Vegas, police said.

At 7.06pm, the teen boy sent a frantic text message to his father, who is in the midst of a divorce battle with Miley, according to the father's lawyer.

'Call me now,' the message read, according to the Las Vegas Review-Journal.

It continued: 'I need help. Mom punched me in the mouth and hit me in the head while I was driving. I (am) bleeding and need you to pick me up. She started screaming around the neighbors and tried falling on me to make it look like I was hurting her.'

Miley was first elected to Family Court in 2004, before being elected to District Court in 2008

The couple's eight-year-old son was also in the car at the time of the incident, the father's attorney said. The attorney reported the incident to police around 11pm after consulting with the father.

Miley was first elected to Family Court in 2004, before being elected to District Court in 2008.

Her husband Edward Miley, a family law and criminal defense attorney, filed for divorce earlier this year, claiming 'catastrophic health issues' and requesting 'spousal support.'

The husband claimed in the divorce filing that the couple have irreconcilable differences, and that the judge had 'conducted herself in such a manner, and taken certain actions, that are improper and inappropriate to the harm and detriment of Edward.'

A response from the judge's attorneys blasted the husband's 'false and defamatory allegations,' which were not further elaborated on in the court filings.

The couple were married in 1997 in Austin, Texas, court records show.

In 2009, Stefany Miley was granted a temporary order of protection against Edward Miley after he was arrested on domestic abuse charges, court records show.

The judge claimed at the time that her husband had been drinking and was abusive to her, a police report stated.

The court papers stated Edward Miley became abusive with the family dog, grabbing the dog by the throat and threatening to kill it.

As Edward Miley was being arrested, he told a police lieutenant that he 'would like you to arrest better looking hookers because I am tired of defending ugly ones.' He could not be reached for comment.

Defense attorney David Chesnoff will represent Stefany Miley against the domestic battery charge. He said on Wednesday afternoon that he had not seen the police report.

'We look forward to representing Judge Miley, who intends on vigorously defending herself against these mere allegations,' Chesnoff said in a statement.

Miley was booked under her maiden name, Stefany Tewell. She is next due in court on January 22.
