A distressing post by an American woman on Facebook helped in her rescue after she and her son were held captive in their home and abused for days.
On Friday, the woman posted a message on Facebook saying she feared that she would be "dead by morning."
Officers then went to her home in Utah, western US, and encountered Troy Critchfield, 33, Fox News reports.
The woman told police that the woman had been choked when she tried to leave the house, and her son's phone had been broken, leaving her unable to call for help.
She eventually managed to sneak into a closet with a laptop and post the message on the social networking site.
Critchfield was booked into Salt Lake County Jail on charges of suspicion of aggravated kidnapping, forcible sodomy, aggravated assault, domestic violence in the presence of a child, damaging a communication device, and child abuse.
