OWASSO, Oklahoma - Police are investigating after they say a person broke into an Owasso family's home at The Greens Apartments and went into their daughter’s bedroom.

Police said they received a 911 call around 3:30 a.m. after a 12-year-old girl woke up screaming to find a person standing over her while in bed. When her parents checked on her the person had fled through the bedroom window.

"Went into the bedroom, and her daughter said she woke up in the middle of the night to find someone in her bedroom," said Deputy Chief of Police Jason Woodruff. 

"Definitely very concerning, something we are taking very seriously."

Police said no one was harmed, but there was evidence found inside and outside of the home indicating that someone got into the room through an unlocked window.

"There was some evidence of some forced entry through an open window in the child's bedroom as well as some muddy footprints," Woodruff said.

“Be extra cautious right now because it's very concerning,” said Deputy Chief Jason Woodruff. “It’s obviously frightening to this family and frightening to any family who hears about this story."

After the call police searched the surrounding areas with officers as well as conducting a K-9 search yet were unable to find the person.

Police are looking into possible surveillance of the area and want to remind people to lock their doors and windows.

Woodruff said the 12-year-old girl did exactly the right thing.

"If you are in danger, you scream for help - try to find an adult and try to contact the police," he said.

Police also ask anyone that might have information to give them a call at (918)-227-2244.
