DALLAS — Dallas police are investigating a sexual assault in the M Streets district on Friday night. Investigators said a man knocked on the victim's apartment door on Martel Avenue; when she opened the door, he pointed a gun at her.
The man sexually assaulted the victim, then hogtied her with cords and duct tape. The suspect stole beer out of her refrigerator and also took her cell phone. The victim told police she had seen the man in her apartment complex a few days earlier.
One week earlier, police were called to an apartment on Gaston Avenue. The armed suspect in that case knocked on the victim's door and then sexually molested her. The suspect also stole items from the woman's refrigerator and some electronics.
In both cases, the suspect was a Latin male with tattoos on his arms, but police aren't saying whether the cases are linked.
