A Shreveport man is behind bars today after pulling a gun on his pregnant girlfriend after finding out she was unfaithful. Chester Brown, 33, was arrested this weekend for aggravated assault and domestic abuse. After finding out his pregnant girlfriend had been unfaithful, Brown became unconsolably enraged. During his rage, Brown grabbed two things, both leading him directly to a prison cell. In one hand, Brown grabbed a handgun, and grabbed a phone with the other.
