Portwood was arrested Monday and jailed under a 24-hour hold until Tuesday afternoon.
Detective Mitch Carroll tells The Herald Bulletin that the child neglect charges stem from Portwood's then-1-year-old daughter being present during two filmed instances of domestic violence.
The Associated Press left a telephone message seeking comment Tuesday at the office of Portwood's attorney Robert Schembs.
Anne Houseworth of the Indiana Department of Child Services said dozens of viewers called the state's child abuse hotline to report Portwood's outbursts.
