In Wake County, a couple who lives in a house near Wendell said a young woman knocked on the door just before midnight and claimed she had car trouble.
"Then two or more males pushed their way in the house and took some property out of the house, robbed them, and then left," Sheriff Donnie Harrison said.
Investigators said the men restrained the couple.
Because no one has been arrested, the couple was too nervous to talk about the home invasion on camera.
Authorities also would not provide additional information about what happened inside the home.
"I'd rather not because we're still under investigation and some of that stuff only they know and we know," Harrison said.
Deputies are also investigating another home invasion near Knightdale.
Earlier this week, deputies said, someone knocked on the door of an apartment resided by a female. When the female answered the door, three men rushed into the apartment and robbed the place.
Investigators said the home invasion may be drug-related.
Investigators in Franklin County also are looking into a similar home invasion.
Authorities in both counties said people should be aware of the situation and residents should be cautious when opening the door to someone they do not know.
"Especially late at night, if someone comes to your door, the best thing to do is talk through the door," Harrison said. "And if they have car trouble, say, 'We'll call the police for you.'"
While all three cases have some similarities, Harrison said the home invasions do not appear to be related.
Still, he said, deputies in Wake and Franklin counties are comparing notes as part of their investigation.
