DALLAS — The Dallas Police Department says former Texas Lt. Gov. David Dewhurst was taken into custody Tuesday afternoon and charged with misdemeanor family assault.

The department says about 5:17 p.m. officers arrived at a home located on W. Mockingbird Lane in Dallas and met with an unidentified woman who says she was physically assaulted by a man known to her.

Dewhurst, 75, was booked into Dallas County Jail.

The department’s Public Integrity Unit is investigating the case.

Dewhurst, a Republican, served as the 41^st lieutenant governor of Texas from 2003 to 2015. He was also Texas land commissioner from 1999 to 2003.

In 2012, Dewhurst ran for the U.S. Senate seat vacated by Republican Kay Hutchinson but lost the primary election to Sen. Ted Cruz.

Dewhurst in 2014 lost his bid for a fourth term as Texas lieutenant governor to current Lt. Gov. Dan Patrick.

According to the Associated Press, in May 2020 Dewhurst’s girlfriend was arrested on charges of injuring him in an alleged attack that left him with two broken ribs.

Dewhurst called police when X-rays confirmed his injuries, said Mary McFaden, the division chief of family criminal law at the Harris County District Attorney’s Office. Leslie Ann Caron, then 40, was charged with injury to an elderly person, a third-degree felony in Texas.
