Detectives say they are working seven cases inside the Fayetteville city limits alone.
"I just think it's terrible," Fayetteville resident Zelekah McClam said. "They need to put more into patrolling the streets at night so they can catch this person."
The attacks have been mostly in apartments complexes.
Investigators say in each case, the incident happened when a woman was home alone. All took place between 10 p.m. and 7:30 a.m., and the suspect was a black male who was 5' 9" or above with a thin/average build. Victims say their attacker wears a mask or bandanna.
"We started getting reports of home invasions," said Theresa Chance with the Fayetteville Police Department. "Once the suspect gets in to the home, he is raping the women. They have all so far been confirmed as females home alone."
One woman, who is not a victim, says she lives alone and bought a pit bull to feel safer. Now she is thinking about buying a gun.
"I'm going to do whatever it takes to maintain my feeling of security in my home," she said. "No one should have to feel afraid or scared in their own home."
Police say they are also looking into reports of similar attacks in Hope Mills and Fort Bragg.
All three agencies are working together to try and identify the person or persons responsible. They say residents should call 911 right away if they notice suspicious activity. Residents should also keep windows and doors locked, keep a phone handy for emergencies, and let friends and family know where you're going and expect to return.
Anyone who can help identify the suspect is asked to call Detective J. Rodriguez with the Fayetteville Police at (910) 433-1856.
