A man arrested in an attempted sexual assault and carjacking in Richardson could be a suspect a sex assault in the M Streets area of Dallas, police said.
The man was arrested Wednesday night after he allegedly forced his way into a woman's apartment, tried to assault her and then tried to carjack a nearby driver.
The victim fought him off and got out of the apartment.
Police said the man then ran across the street and tried to carjack Baravan Haji. Haji said the man put a gun in his face and told him to move over into the passenger seat.
"He wanted to take off with me in the car," Haji said, who then turned the gun on the man and punched him.
Police said the man ran off and tried to hide in a garage but was soon arrested.
Dallas police are looking into whether he sexually assaulted a woman in the M Streets neighborhood last week. Richardson police said his description and modus operandi are similar to that of the attacker in the Dallas case.
Police are not releasing the man's name or mugshot until Dallas detectives have a chance to speak with him.
"I don't keep my pepper spray on my key chain, but I would probably put it back on my key chain if I heard my neighborhood was getting a little more dangerous and probably wouldn't come here at night," said Mary Schuckhart, who lives in M Streets.
Richardson police also said the suspect could be connected to a Friday homicide nearby on St. Paul Drive, which would take precedence over the sexual assault cases.
The man remained in Richardson police custody Thursday night.
