Dallas Mavericks' Assistant Coach Arrested for Allegedly Assaulting Woman with a Gun: Reports

An assistant coach for the Dallas Mavericks has been accused of hitting his girlfriend with a gun, according to reports. 

At around 3:45 a.m. local time on Saturday, Feb. 15, Dallas police were called to the 1000 block of Ross Avenue, according to local publication The Dallas Morning News. Darrell Armstrong, 56, was arrested and charged with aggravated assault with a deadly weapon at the scene, having allegedly hit a woman with a gun and threatened to shoot her, per the outlet.

The victim — who was identified as his girlfriend in an arrest warrant affidavit, per The Dallas Morning News — allegedly left the apartment and went to call her family and police after being struck on the right side of her face. Per the outlet, Armstrong had been drinking in their shared apartment when an argument broke out about him receiving a text from another woman.

Dallas Fire Rescue treated her at the scene, CBS News reported.

A spokesperson for the Dallas Mavericks revealed in a statement to the outlet that they were aware of an incident “involving a member of our staff.”

“We take this matter seriously. The employee has been placed on administrative suspension pending the outcome of legal proceedings,” the statement read, per CBS News.

“This matter is currently under review by the appropriate legal authorities,” the statement continued. “Due to this fact, we will allow the legal process to run its course and we will refrain from further comment while proceedings are ongoing.”
