Residents of Indian Head Park in suburban Cook County were warned to lock their doors after a girl was reportedly attacked by a knife-wielding intruder on Wednesday night.

Police did not release the age of the girl, who told police she was home alone at around 6:45 p.m. when she heard noises on the first floor of the house, Indian Head Park Police Sgt. Raymond Leuser said. The girl said she went downstairs, where she found a white male wearing a mask in her kitchen, Leuser said.

The suspect attacked the victim, cutting her right arm with a knife, said Leuser, who categorized the wound as superficial. The intruder then fled the home.

Police said there were no signs of forced entry, and officers who searched the area were unable to locate a suspect.

Following the alleged home invasion, authorities sent a test message to residents stating, "Home invasion on Briarwood in IHP w/injuries. Suspect is still at large. You are urged to lock their doors and keep outside lights on. Area police alerted," according to WGN.

The Indian Head Park Police Department was assisted by Cook County Sheriff, Cook County Forest Preserve and Countryside police departments. The Indian Head Park Major Crimes Assistance Team is continuing to investigate the incident, Leuser said.
