(CNN) -- A North Carolina man is accused of arranging to have his wife raped through personal ads on the Web site Craigslist, police said Wednesday.

The 25-year-old man, of Kannapolis, North Carolina, was arrested in connection with the incident that occurred at his home early Sunday, police said in a statement.

Police responded to the home at about 2:45 a.m. after receiving a 911 call indicating a male armed with a knife appeared in the couple's bedroom and sexually assaulted the man's wife, authorities said.

The man was present at the time of the assault, and two young children were in the home, but were unharmed and unaware of the incident, the police statement said.

"During the investigation, investigators interviewed the victim and her husband," the statement said. "Investigators became suspicious when they noticed there was no sign of forced entry to the home. Investigators also developed information that led them to note specific inconsistencies in the initial statement provided by [the man]."

But on Tuesday, police found that the man "had responded to at least two personal ads on Craigslist.com in an effort to arrange for someone to come to his home and have sex with his wife using some type of scare tactic."

"Investigators believe [he] arranged this incident without the knowledge or consent of the victim," the police statement said.

The woman was taken to a hospital after the assault, where she underwent a forensic examination and was interviewed, police said. She suffered no serious physical injuries and was released shortly afterward.

Police did not release the identity of the victim. CNN is not naming the victim's husband in an effort to avoid identifying her. The incident remains under investigation, police said.

The man faces charges including first-degree rape, two counts of first-degree sexual offense and one count of attempted first-degree sexual offense, according to the police statement.

Kannapolis is about 26 miles northeast of Charlotte, North Carolina.
