Rich Dollaz has his daughter Ashley Trowers‘ back after her arrest for allegedly shooting at her ex in Memphis … insisting she’s a domestic violence victim who acted in self-defense.

The “Love & Hip Hop” alum hopped on “TMZ Live” Monday and emphatically claimed Ashley only fired out of fear, and added she and her child’s father have had multiple domestic disputes in the past.

TMZ Hip Hop broke the story … cops say Ashley was approached by the ex, Demiah Tatum, and his friend Mykel Yates during her first day working security at a Kroger’s, and she ended up firing 2 shots at the vehicle.

Rich says Ashley already had a temporary restraining order requiring Demiah to stay away from her — but he claims Demiah got out of his car to confront her.

Rich says people have told him Demiah’s claiming he just happened to “pull up” at the Kroger’s where Ashley worked … but her dad isn’t buying it was a total coincidence.
